Super hybrid wisdom flagship SUVPHEV

Hongqi HS7 PHEV is equipped with the latest "super hybrid" technology of Hongqi brand, and cooperates with HDU35 high-efficiency hybrid special motor with the highest speed of 20,000 r/min. The maximum power reaches 358kW, which can explode strong power in a very short time. The acceleration time of the vehicle is only 6.8s per 100 kilometers. Combined with the excellent tracking performance of the front four-wheel drive system, it can help the vehicle to drive out of the muddy road easily and smoothly, and bring full confidence to the driver.

Red flag HS7 PHEV is a variety of driving modes.The plug-in hybrid system supports "4 engines and 8 modes", that is, pure electric front drive, pure electric rear drive, direct engine drive and hybrid drive, etc. It is not necessary to adjust one by one according to the field environment, just choose the driving mode, and all the rest will be controlled by the computer.The following are the power output and energy distribution in different modes:

Pure electric four-wheel drive/two-wheel drive mode：power take offMainly relying on the motor to provide power, in the pure electric four-wheel drive mode, the front and rear motors work together to output strong torque, which makes the vehicle have excellent acceleration performance and dynamic response, and can bring a quiet and rapid driving experience, which is suitable for low-speed driving on urban roads or scenes that require high quietness.

Energy distributionAccording to the driving state of the vehicle and the driver’s operation, the output power of the front and rear motors is intelligently distributed. For example, when driving smoothly, the power distribution of the front and rear motors is relatively balanced to ensure the stability of the vehicle; In the case of acceleration, climbing or high-speed cornering, the output power of the front and rear motors will be adjusted in real time according to the dynamic demand of the vehicle, for example, the power output of the rear motor will be increased to enhance the traction and handling of the vehicle.

Series four-wheel drive/two-wheel drive mode：power take offThe engine is mainly used to drive the generator to generate electricity, and the generated electricity is supplied to the motor-driven vehicle. At this time, the motor is still the main power source, and the power output characteristics are similar to those in pure electric mode, with good dynamic response and acceleration performance. This mode is suitable for the situation that the battery power is insufficient but still needs a certain power output, for example, when the battery power is gradually reduced during long-distance driving.Energy distributionThe output power of the engine is mainly used for power generation. According to the power demand of the vehicle and the state of the battery, the control system will automatically adjust the engine speed and power generation to ensure stable power supply to the motor. At the same time, according to the driving conditions of the vehicle, the electric energy will be reasonably distributed to the front and rear motors to ensure the dynamic performance and driving stability of the vehicle.

Energy recovery four-wheel drive/two-wheel drive mode：power take offWhen the vehicle is decelerating or braking, the motor is switched to the generator working mode, and the kinetic energy of the vehicle is converted into electric energy and stored in the battery. At this time, the power output is mainly used to achieve the braking effect, not to drive the vehicle forward. Through energy recovery, the utilization rate of energy can be effectively improved and the cruising range of vehicles can be increased.

Energy distributionIn the process of energy recovery, both front and rear motors will participate in kinetic energy recovery. The control system will dynamically adjust the energy recovery of the front and rear motors according to factors such as the braking intensity of the vehicle, the vehicle speed and the charging state of the battery. For example, when braking suddenly, the front and rear motors may recover energy with greater power; When slowing down slowly, the energy recovery power is relatively small to ensure the stability and comfort of braking.

Parallel four-wheel drive/two-wheel drive mode：power take offThe engine and motor work at the same time to provide power for the vehicle. In this mode, the advantages of engine and motor can be brought into full play, and powerful power output can be achieved. It is suitable for high-speed driving, overtaking and scenes requiring large power reserve, such as when overtaking quickly on the expressway.

Energy distributionAccording to the driving demand of the vehicle and the working state of the power system, the control system will adjust the energy distribution ratio between the engine and the motor in real time. Under normal driving conditions, the engine and the motor may jointly output power according to a certain proportion to give consideration to power performance and fuel economy; When a large power output is needed, such as sudden acceleration or climbing, the motor may provide a large auxiliary power to work with the engine to make the vehicle obtain stronger power performance.

The maximum power of the motor at the rear axle of the vehicle reaches 70kW, which can ensure the posture of the vehicle body in the state of rapid acceleration, the stability under complex working conditions and enhance the comfort. On the other hand, this setting is based on the four-bar rear suspension. Compared with some other suspension structures, it can give priority to locking the comfort foundation in effect and avoid the risk of mashup caused by complex adjustment. For example, in Altay, where the mountainous area accounts for one-third of the total area, the gravel road surface passing through the test drive often causes strong car body vibration and bumps. Thanks to the IDCS intelligent variable damping and shock absorption function carried by Hongqi HS7 PHEV, the whole car can monitor the road surface and car body posture in real time, automatically adjust the front and rear damping distribution, and realize a smooth and comfortable driving experience throughout the journey, thus enhancing the comfort and stability.

In terms of fuel consumptionThis car is equipped with a plug-in hybrid system consisting of a 2.0T engine and a motor, which ensures power performance and achieves better fuel economy through hybrid technology.245. In addition, it has a "four engines and eight modes" driving mode, which can switch between pure electric four-wheel drive/two-wheel drive, series four-wheel drive/two-wheel drive, energy recovery four-wheel drive/two-wheel drive and parallel four-wheel drive/two-wheel drive, and can automatically optimize power output and energy distribution according to different driving conditions, further reducing fuel consumption.

No matter how much power, space or long-lasting endurance stability far exceeds that of the same model, going out instead of walking or traveling by car is versatile and labor-saving, so we have to praise the light of domestic products.
