Embodiment 1

[0029] An embodiment of the present invention provides a coasting energy recovery method, which is applied to a coasting energy recovery system of a hybrid vehicle. Specifically, it can be executed on a controller of the coasting energy recovery system to recover coasting energy. The energy recovery system is It refers to recycling the excess energy consumed by the vehicle during braking or deceleration, so as to reduce the energy consumption of the vehicle and increase the mileage of the hybrid vehicle.

[0030] Such as figure 1 A flow chart of a coasting energy recovery method shown includes the following steps:

[0031] Step S102, obtaining the driving parameters and slope signal of the current vehicle; usually, the driving parameters include vehicle speed, gear position and brake pedal signal;

[0032] During specific implementation, the vehicle speed and gear position signals can be measured by a speed sensor, and the brake pedal signal can be detected by a brake pedal o...

Embodiment 2

[0074] On the basis of the above embodiments, the embodiment of the present invention also provides a taxiing energy recovery device, which is installed in the taxiing energy recovery system to recover taxiing energy, such as image 3 A structural schematic diagram of a taxiing energy recovery device shown, the device includes:

[0075] The obtaining module 30 is used to obtain the driving parameters and slope signal of the current vehicle; wherein, the driving parameters include vehicle speed, gear position and brake pedal signal;

Abstract

The invention provides a sliding energy recycling method, device and system, and relates to the technical field of vehicles. The method comprises the steps of obtaining driving parameters and slope signals of a current vehicle, wherein the driving parameters comprise vehicle speeds, gears and brake pedal signals; according to the driving parameters, calculating initial recycling torque at the current vehicle speed; correcting the initial recycling torque according to the slope signals to obtain target recycling torque; sending the target recycling torque to a motor to trigger the motor to recycle energy. According to the sliding energy recycling method, device and system, in the process of energy recycling, the initial recycling torque can be corrected according to road signals, and the problems are solved that an accelerator is frequently pedaled when the vehicle deceleration is too high in the upslope process of the vehicle or a brake is frequently pedaled when the vehicle deceleration is too low in the downslope process; the method helps to guarantee the driving comfort of the vehicle.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a sliding energy recovery method, device and system. Background technique [0002] With the increasing popularization of hybrid electric vehicles, the number of hybrid electric vehicles is increasing day by day. The energy saving and battery life of hybrid electric vehicles have been paid great attention by domestic and foreign automotive engineering circles. In order to protect the environment and use resources rationally, it is necessary to reduce the resource consumption of hybrid electric vehicles. Generally, recovering the energy lost when the hybrid vehicle brakes and reusing it when the hybrid vehicle accelerates or goes uphill can improve the endurance of the hybrid vehicle. [0003] Generally, hybrid vehicles are equipped with a sliding energy recovery system. During driving, when the driver releases the accelerator, the vehicle achieves a deceleration effect by ove...
