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...
