Title:
DRIVE-BY-WIRE VEHICLE, MECHANICAL-HYDRAULIC COMPOSITE BRAKING AND GEAR SHIFTING INTEGRATED SYSTEM, AND CONTROL METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/174487
Kind Code:
A1
Abstract:
The present invention provides a drive-by-wire vehicle, a mechanical-hydraulic composite braking and gear shifting integrated system, and a control method therefor. The braking and gear shifting integrated system comprises a gear shifting module, a brake-by-wire module, a power distribution module, and a control assembly module. The gear shifting module comprises a gear shifting assisting submodule and a gear shifting execution submodule. The gear shifting assisting submodule is used to store and reuse a braking force of a driver stepping on a brake pedal in a brake-by-wire process to assist in gear shifting. The gear shifting execution submodule is used to implement automatic mechanical gear shifting. The brake-by-wire module is used to implement brake-by-wire. The power distribution module is used to distribute an electric motor torque in a redundant process. The control assembly module controls, by reading a gear shifting signal, a brake signal, and a current signal fed back by each electric motor controller, operation of each gear shifting electric motor and each brake electric motor, lock or release of a brake, and the turning on/off of a solenoid valve, so as to realize switching between different operating modes to meet the requirements of different operating conditions and ensure system security, stability and reliability.
