Abstract
The invention provides a method, device and vehicle for determining energy recycling of a hybridelectric vehicle. The method for determining the energy recycling of the hybridelectric vehicle comprises the following steps: collecting a running state decision signal of the vehicle, wherein the running state decision signal comprises at least one of an accelerator pedal opening signal, a brake pedal opening signal, a brake switch signal, a high-pressure system running state signal, a vehicle speed signal and a brakesystem state signal; determining the running state of the vehicle according to the running state decision signal, wherein the running state comprises a sliding state, a braking state, a high-speed accelerator releasing state and a brake fault state; executing an energy recycling policy corresponding to the running state according to the running state of the vehicle, thereby acquiring a torque value of to-be-recycled energy. According to the method, the running state of the vehicle is determined and the energy recycling policy corresponding to the running state is performed according to the determined running state, so that the recycling rate of energy is increased and the use ratio of energy is increased.
Description
technical field [0001] The invention relates to the technical field of hybrid electric vehicles, in particular to a method and device for determining energy recovery of a hybrid electric vehicle and the vehicle. Background technique [0002] Due to the advantages of environmental protection and energy saving of hybrid electric vehicles, the industry of hybrid electric vehicles has begun to develop rapidly. Studies have shown that under urban driving conditions, about 1 / 3 to 1 / 2 of the energy is consumed in the braking process. Due to the driving characteristics of hybrid electric vehicles, when braking and decelerating, the braking Kinetic energy can be converted into electrical energy and stored in the power battery (called braking energy recovery) to reduce energy consumption, improve energy utilization efficiency and extend driving range, and at the same time have the benefit of extending the service life of the braking system . [0003] The current braking energy recov...
