However, the starting of electric vehicles is quite different from that of fuel vehicles. Fuel vehicles can judge the starting situation through the sound of engine feedback, while electric vehicles are powered by the power battery to the motor. Since the motor is running, the sound is very small. Negligible, so it is not appropriate to use the sound as the basis for judging the start; therefore, how to safely and stably control the start of the electric vehicle has become a subject that all car manufacturers need to study

The invention provides a control system for keyless safety starting of an electric vehicle. The control system comprises a vehicle body control module, a battery management module and a power battery module, wherein the vehicle body control module detects and judges whether a starting condition signal meets the safety starting requirement of a motor and transmits a starting confirmation request to the battery management module when the starting condition signal completely meets the safety starting requirement; and the battery management module controls the power battery module to supply powerto the motor according to the starting confirmation request. The control system for the keyless safety starting of the electric vehicle improves the starting stability, has the characteristics of lowcost and high universality and also improves the stability for the operation of the electric vehicle. The invention also provides a keyless safety starting system for the electric vehicle and a control method for the keyless safety starting of the electric vehicle.
Description
technical field [0001] The invention relates to a control system for keyless safe starting of electric vehicles, a keyless safe starting system for electric vehicles and a control method for keyless safe starting of electric vehicles. Background technique [0002] The keyless safe start system has been widely used in fuel vehicles. As a new option to replace the traditional ignition key and ignition lock, the driver only needs to press the start button or switch to complete the engine start. It is easy to operate, safe and stylish, more in line with the trend of intelligent automotive electronics, and has begun to be widely used in high-end cars at home and abroad. [0003] In recent years, in order to reduce energy consumption and environmental pollution caused by fuel vehicles, electric vehicles have developed rapidly. However, the starting of electric vehicles is quite different from that of fuel vehicles. Fuel vehicles can judge the starting situation through the sound ...
