Abstract

The invention discloses a braking energy recovery device of an automatic driving automobile, which comprises an automobile control system, an external input system, a flywheel regenerative braking system, a storage battery system, a motor control system, a mechanical braking system and a transmission system, the external input system is used for detecting a to-be-braked distance; the mechanical braking system is used for mechanically braking the vehicle; the flywheel regenerative braking system is used for providing driving torque and braking torque for the transmission system and recycling braking energy in the braking process. The vehicle control system controls the vehicle to adopt a flywheel regenerative braking system for braking in a first braking state and adopt a mechanical brakingsystem for braking in a second braking state according to the to-be-braked distance; braking of the vehicle can be achieved without manual control, the flywheel regenerative braking system or the mechanical braking system can be directly controlled by the vehicle control system to brake the vehicle, part of braking energy can be recycled through the flywheel regenerative braking system, and the energy utilization efficiency is improved.

Description

technical field [0001] The invention belongs to the field of vehicle energy recovery, and in particular relates to a braking energy recovery device for an automatic driving vehicle. Background technique [0002] As far as the current situation is concerned, the existing vehicles generally realize the driving of the vehicle based on the driver's specific operation. For example, when the vehicle is braking, the flywheel regenerative braking system will judge the driver's input through the control system based on the driver's input to the brake pedal. Depending on the depth of the brake pedal, different strategies are invoked to perform energy recovery operations. [0003] However, with the development of automatic driving technology, the level of automatic driving continues to improve, and even when it reaches the L4 / L5 level, the vehicle has abandoned the brake pedal. When braking, the VCU directly controls the mechanical braking system through the CAN bus for braking, while ...
