Vehicle control apparatus

Abstract

A vehicle control apparatus 100 includes: a steering control unit 30 connected to an in-vehicle communication network 10 mounted on a vehicle 1 and configured to control a steering motor 3b configured to add an auxiliary torque corresponding to a steering operation by a driver to a steering mechanism; and an illegal signal detection unit 50 connected to the in-vehicle communication network 10 and configured to detect an illegal signal input to the in-vehicle communication network 10. The steering control unit 30 performs torque restriction of the steering motor 3b for restricting the auxiliary torque of the steering motor 3b when the illegal signal is detected by the illegal signal detection unit 50.

Description

technical field [0001] The present invention relates to a vehicle control device for controlling a steering mechanism of a vehicle. Background technique [0002] Conventionally, there is known a device that detects a DoS attack (Denial of Service attack) on an in-vehicle communication network from a device outside the vehicle (for example, see Patent Document 1). In the device described in Patent Document 1, when it is determined that a DoS attack has occurred, the relay of the data signal by the gateway to each electronic control device is stopped. [0003] However, in the device described in Patent Document 1, the gateway stops the relay of the data signal only when it is determined that it is a DoS attack, and does not take into account the influence of the illegal signal input before the determination on the vehicle. Therefore, due to these signals, unnecessary assist torque may be generated by the steering mechanism of the vehicle, and unintended steering force may be ...

Problems solved by technology

[0003] However, in the device described in Patent Document 1, the gateway only stops the relay of the data signal when it is determined that it is a DoS attack, and does not take into account the impact of the illegal signal input before the determination is made on the vehicle.

Therefore, due to these signals, it is possible that the steering mechanism of the vehicle may generate unnecessary assist torque and unintentional steering force
