Abstract

The invention discloses a vehicle engine starting anti-theft authentication control strategy with an intelligent key detection function. The vehicle engine starting anti-theft authentication control strategy specifically comprises the steps that a PEPS controller sends an engine starting request to an EMS controller, the EMS controller generates a random challenge code, the random challenge code is sent to the PEPS controller, and an encryption result y3 is generated according to the random challenge code and an ESK code; the PEPS controller generates an encryption result y4 and an intelligent effective key detection result according to the received information and the ESK code in the PEPS controller, and feeds back the encryption result y4 and the intelligent effective key detection result to the EMS controller; and the EMS controller determines whether to start the engine or not by judging the detection result of the intelligent effective key and comparing y3 with y4. The risk that the vehicle is stolen is reduced, and the safety performance of the vehicle is improved.

Description

technical field [0001] The invention relates to the field of vehicle anti-theft authentication, in particular to a vehicle engine startup anti-theft authentication control strategy with a smart key detection function. Background technique [0002] With the continuous development of science and technology, car owners have higher and higher requirements for cars, and at the same time, they have higher and higher requirements for the safety performance of cars. Among them, when the car is started, the PEPS controller will send an engine start request signal to the EMS controller, and when the EMS receives the request signal from the PEPS, it will control the engine start. However, when the EMS receives an illegal engine request signal (when a signal is sent to the EMS controller through a certain device) and the smart key is not detected in the car, at this time, it is very dangerous if the EMS controls the engine start. At present, the EMS anti-theft authentication is mostly ...
