[Test Drive] Hyundai's 'The All New Palisade HEV'... Next Generation Hybrid No. 1

Hyundai Motor Company's flagship sports utility vehicle (SUV) Palisade is equipped with a next-generation hybrid (HEV) system and is targeting the rapidly growing hybrid market. This is the first time that a Palisade model has been equipped with a hybrid powertrain (power unit).

The 'The All New Palisade HEV' model combines fuel efficiency, stable driving performance and ride quality, spaciousness, and the convenience of an electric vehicle. The Palisade, which has returned with a completely new look after six years, is the first model to feature Hyundai Motor Group's next-generation hybrid system.



In terms of appearance, there is no significant difference from the existing gasoline model. The 18-inch alloy wheels of the Exclusive trim are distinguished as a design exclusive to the HEV, but the test drive model, the 7-seater Calligraphy, is equipped with 21-inch wheels, which are the same as the gasoline model.



When you press the start button of the column-type electronic gear shifter reminiscent of an electric vehicle, the word 'READY' is displayed on the instrument panel. The engine is started and ready to drive, but since the engine is not running, it is as quiet as an electric car. When you put the gear in 'Drive (D)' and take your foot off the brake pedal, it starts smoothly. Especially when driving in EV mode at low speeds, it moves briskly like an electric car, even though it is a large SUV with a body length of 5 meters and a weight of over 2 tons.



After that, it starts driving in earnest and the engine wakes up and starts intervening. Since driving in EV mode is so quiet, the engine noise is relatively loud when the engine is running. However, the NVH (Noise, Vibration, and Discomfort) countermeasure design effectively controls road noise and wind noise while driving, maintaining interior quietness.

The battery is charged through regenerative braking. In Hyundai Motor Group's next-generation HEV system, the electric motor that starts the engine is directly connected to the engine to increase efficiency, and the motor also assists the engine during driving.



The electric motor, which is mainly responsible for driving and regenerative braking, has improved power performance by increasing the output from 47.7 kW (kW) to 54 kW compared to the electric motor applied to the existing Santa Fe HEV, and has also increased the amount of regenerative braking. In addition, the two motors assist in driving in the optimal engine efficiency range, helping to improve fuel efficiency.



The Palisade HEV is based on the same gasoline 2.5 turbo engine as the gasoline model. The system output using the two electric motors reaches 335 horsepower. This is a level that far exceeds the gasoline 2.5 turbo model (281 horsepower) or the old 3.8 gasoline model (295 horsepower). The output has improved by 42% compared to the output of the 1.6 turbo hybrid system currently applied to the Santa Fe HEV.



The fuel efficiency of the All New Palisade gasoline 2.5 turbo model with 18-inch tires and two-wheel drive (2WD) is 9.7 km/ℓ combined. Under the same conditions, The Palisade HEV's fuel efficiency is 14.1 km/ℓ, which is a significant improvement in terms of power performance and efficiency compared to the gasoline model. Based on the fuel tank capacity, a simple calculation shows that it can travel up to 1,015 km on a single tank. It



also boasts a smooth ride and stable driving performance. The 'E-Motion Drive' technology, which utilizes the hybrid system's drive motor, complements the ride quality and creates more agile movements when turning corners.

Large SUVs have many advantages as family cars, but there are often times when you feel regret due to their low fuel efficiency. However, the All New Palisade HEV is equipped with a hybrid to increase fuel efficiency and adds advantages that only electric vehicles can have.



For example, 'E-handling' was applied to shift the center of gravity by controlling the drive motor when the car turns, increasing steering response and stability. Thanks to this, it was possible to suppress roll and drive in a stable posture in turning driving situations such as highway ramp sections. In addition, The dynamic torque vectoring control (e-DTVC) technology, which improves handling performance through bias braking and drive motor torque compensation, also contributes to this solid movement. Together with the rack-mounted power steering (R-MDPS) that improves steering responsiveness, these are all elements that add to the fun of driving.

When going over bumps, the preview electronically controlled suspension (ECS) applied for the first time to a Hyundai SUV and the 'E-Ride' technology stand out. This suppresses the pitch phenomenon that occurs when passing through acceleration/deceleration and speed bumps by controlling the torque of the drive motor. In fact, the Palisade HEV maintained a stable posture without unnecessary body movement when going over speed bumps.



The 'Stay Mode' that was first applied to the Palisade HEV is also impressive. When spending time in the car and wanting to use electric devices, the engine must be idled to prevent discharge of the internal combustion engine vehicle. However, the resulting fuel consumption reduces efficiency and also causes noise, vibration, and heat generation. However, Stay Mode can use electricity like an EV without the need for idling. In particular, if you set Stay Mode in advance when you reach the destination set in the navigation, it will adjust the battery charge while moving to secure as much power as possible.

The trunk has an indoor V2L terminal, which is seen in electric vehicles. V2L can be said to be an outlet that allows 220 volt (V) electrical products to be used in the car. Compared to the 220V inverter specifications provided as a new car option for the gasoline 7-seater model, the output is much higher and there is less concern about battery discharge. The numbers 250V and 16A written on the V2L cover are the same as those seen in Hyundai EVs. It looks good to use as a power source for outdoor activities such as camping.



The 'All New Palisade HEV' is a key model of Hyundai Motor Group's strategic portfolio based on multi-powertrains to further enhance the competitiveness of not only electric vehicles but also internal combustion engine vehicles and to flexibly respond to the rapidly changing market environment. The HEV system applied to the Palisade HEV will be sequentially applied to other models of Hyundai and Kia in the future.

Livestock Manure Methane Is Soaring, But 'Resource Recovery' Isn't Working [Now is a Climate Crisis]

이미지
It has been pointed out that the methane emissions from the livestock waste treatment process were actually reported to be 2.5 times smaller than the previous calculation standards. It is expected that livestock waste will increase rapidly in the future, but an analysis report has been released that 'biogasification', which turns it into a resource, is only at the 10% level. It is urgent to come up with countermeasures as methane, one of the greenhouse gases, is expected to increase rapidly. According to the analysis of the entire livestock waste treatment process for the first time in Korea, the largest source of methane emissions was pigs (73%), and only 14% of pig waste was used for biogas in the public sector. It has been pointed out that it is urgent to come up with countermeasures as methane from livestock waste is increasing rapidly but 'resource conversion' is insufficient.

Brain visual cortex selective processing, AI image recognition ability

이미지
A smarter AI technology that resembles the human brain has emerged. The research team led by Director Lee Chang-joon of the Cognition and Sociality Research Group at the Institute for Basic Science (IBS, President Noh Do-young) and the research team led by Professor Song Kyung-woo of the Department of Applied Statistics at Yonsei University have developed a new technology that enhances the image recognition capabilities of AI by applying the way the brain's visual cortex selects and processes visual information. The human visual system has excellent recognition capabilities. It can recognize objects at a glance and quickly select important information even in complex environments. Existing AI models still show limitations. In the actual brain's visual cortex, neurons are widely and smoothly connected based on the center. This connection strength shows the characteristic of gradually changing with distance (a, b). On the other hand, in existing convolutio...
