Embodiment Construction
[0094] Exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that the application will be more thoroughly understood, and will fully convey the scope of the application to those skilled in the art.
[0095] Energy recovery can convert the wasted energy forms that cannot be stored and reused, such as thermal energy, mechanical energy, light energy, etc., into electrical energy for storage and reuse. The motor of the new energy vehicle can work in the power generation mode, so the kinetic energy can be converted into electric energy and stored in the battery during the coasting or braking process to realize energy recovery. Therefor...

The invention provides a vehicle control method and device, electronic equipment and a storage medium, and is applied to the technical field of vehicles, under the condition that an energy recovery instruction of the vehicle is obtained, the initial sliding recovery torque is determined based on the sliding deceleration of the vehicle, and the target sliding recovery torque is obtained through correction according to a first error factor; an initial brake recovery torque is determined based on brake deceleration of the vehicle, the initial brake recovery torque is corrected according to a second error factor, a target brake recovery torque is determined in combination with a gearbox filtered gear ratio and a pulley train speed ratio, and smoothness of the obtained target brake recovery torque is ensured by using the gearbox filtered gear ratio. The target recovery torque is determined according to the sum of the target braking recovery torque and the target sliding recovery torque, the belt transmission starting / power generation integrated motor is driven to generate power on the basis of the target recovery torque, energy recovery is achieved on the basis of ensuring vehicle running smoothness, and existing resources are fully utilized.
Description
technical field [0001] The present application belongs to the technical field of vehicles, and in particular, relates to a vehicle control method, device, electronic device and storage medium. Background technique [0002] With the continuous development of science and technology, the phenomenon of energy shortage is becoming more and more obvious, and the voices of all countries in the world to develop new energy are getting stronger and stronger. New energy vehicles can reduce fuel consumption and improve drivability by adding a hybrid system on the original traditional vehicle platform. Therefore, the development of new energy vehicles has become an inevitable trend in the current transportation development. [0003] New energy vehicles have the advantages of low emission pollution, high energy efficiency and energy diversification. However, new energy vehicles also face the problem of driving range. In order to maximize the driving range, related technologies have prop...
