VEHICLE CONTROLLER
First Claim
1. A vehicle controller, comprising:
- an image sensor capturing an image of an area ahead of a vehicle;
a first controller portion executing a first, a second and a third processes for the image captured by the image sensor, the first process being a control for preventing the vehicle from colliding with obstacles ahead thereof, the second process being a control for preventing the vehicle from deviating from a traveling lane, the third process being a control for switching an irradiation state of a light of the vehicle;
a casing in which the image sensor and the controller portion are disposed;
a temperature detector portion detecting a temperature of the inside of the casing or a temperature of the image sensor; and
stopping means for stopping the second and third processes when the temperature detected by the temperature detector portion exceeds a first predetermined threshold, and further stopping the first process too when the temperature exceeds a second threshold set to be larger than the first threshold.

Abstract
When a temperature T detected by a thermistor built inside a camera unit exceeds a preset temperature T1, at least a process, among processes executed by a CPU built inside the camera unit, that relates only to LKA or AHB (such as a white line recognizing process) is stopped. Then, the amount of heat generated by the CPU decreases, whereby the temperature inside the housing also decreases. In this way, even when the PCS control is continuously performed by continuing electric power supply to an imaging element in the camera unit, performance of the imaging element can be maintained in some cases, thus allowing the electric power supply to the imaging element to continue in a satisfactory manner for a long period.
