Title:
VEHICLE CONTROL DEVICE
Document Type and Number:
Japanese Patent JP09226548
Kind Code:
A
Abstract:

To provide a vehicle control device capable of ensuring freedom from the effect of a noise resulting from magnetic field generated due to the heater current or the like of a load heater, upon the superposition of the noise on the wheel speed signal of a speed sensor.

Regarding the vehicle control device equipped with an electromagnetic induction speed sensor laid for each wheel so as to make traction control on the basis of a wheel rotational speed signal outputted from the electromagnetic induction speed sensor, a noise superposition judgement means judges whether an external noise due to magnetic field is superposed on the wheel rotational speed signal outputted the electromagnetic induction speed sensor at steps 2 to 5. In addition, when the superposition of the noise is identified with the judgement means, a vehicular control change means changes at least a part of the traction control at a step 7.
