Embodiment Construction

[0019] figure 1 It is the overall module schematic diagram of the present invention. After the electric door lock of the electric vehicle is opened, the motor identification module 2 in the controller part 1 transmits the key to the controller identification module 4 in the motor part 3 through the bus, and the controller identification module 4 in the motor part 3 receives the key After the key, the confirmation information is sent back to the motor identification module 2 in the controller part 1, and the power supply circuit 5 of the Hall element is turned on at the same time, allowing the motor part 3 to work normally. The controller part 1 turns into a normal working state after the motor identification module 2 receives the confirmation information. If the controller identification module 4 does not receive the key or the key is wrong, and the motor identification module 2 does not receive the confirmation information, both the controller part 1 and the motor part 3 wil...

Abstract

The invention discloses an anti-tampering motor controller and motor inter-identification system. A motor identification communication interface circuit is additionally arranged on a controller part; an identification control circuit is additionally arranged on a motor part; the controller part sends a secret key to the identification control circuit through a bus; the identification control circuit sends back confirmation information to the controller part after receiving the secret key, and switches on a hall power supply control circuit at the same time to send a three-phase hall signal to the controller part and determine a motor phase; the controller part steps into a normal working state after receiving the confirmation information and drives a motor. The system can prevent a controller or the motor of an electric vehicle from being randomly tampered by a buyer, so that the safety performance is improved; the fault rate is reduced; the maintenance and management cost of a manufacturer is lowered.

Description

technical field [0001] The invention relates to a controller and a motor mutual recognition system of an electric vehicle, in particular to a tamper-proof electric vehicle controller and a motor mutual recognition system. Background technique [0002] At present, a major problem in the electric vehicle market has always plagued electric vehicle manufacturers, that is, the sold electric vehicles have been tampered with by some users, dealers or electric vehicle repair shops at will. The tampered components are mainly controllers or motors. The impact is that the safety performance of electric vehicles is reduced, the failure rate increases significantly, and the number of market returns increases, causing huge losses for electric vehicle manufacturers, and it also requires electric vehicle manufacturers to establish a large after-sales service team, increasing labor costs and management costs. Make the whole after-sales service cost very high. There is currently no effective...
