Title:
VEHICLE SAFETY CONTROL METHOD AND SYSTEM WITH POWER SUPPLY SYSTEMS
Document Type and Number:
WIPO Patent Application WO/2018/192271
Kind Code:
A1
Abstract:
A vehicle safety control method with power supply systems. A power supply system is divided into a first-level power supply system (4) and a second-level power supply system (5). When a first safety diagnosis module (1) predetermines that an accident is going to happen, a power source of the second-level power supply system (5) is cut off, a capacitor is discharged, and an emergency braking operation is triggered. After the accident happens, a second safety diagnosis module (2) diagnoses the severity degree of the accident, and selectively uses, according to the diagnosis result, the following operations: recovering power supply of the second-level power supply system (5), controlling the output power of the first-level power supply system (4) and triggering a safety belt pre-tightening operation, or cutting off the first-level power supply system (4), discharging the capacitor, and triggering a safety airbag. By means of the present invention, the dynamic performance of the vehicle can be maintained during slight and medium collisions, such that the vehicle can leave a dangerous area as soon as possible; the whole power supply system can be effectively cut off when a serious collision happens so that electric shock is avoided; and layout requirements for the second-level power supply system are reduced, and the freedom degree of the layout is increased. The present invention also relates to a vehicle safety control system with power supply systems.
