Vehicle control apparatus having function for preventing erroneous operation due to delay in activation of other vehicle control apparatus
First Claim
1. In a control system of a vehicle, a first vehicle control apparatus comprising a communication circuit that is coupled for data communication with a second vehicle control apparatus, and a storage medium for storing data received from said second vehicle control apparatus via said communication circuit, said second vehicle control apparatus being changed from an inoperative condition to an operative condition at an activation time point that is delayed with respect to an activation time point at which said first vehicle control apparatus becomes changed from an inoperative condition to an operative condition;
- wherein said first vehicle control apparatus comprises control circuit means for inhibiting execution of processing that utilizes data stored in said storage medium, during a delay interval extending from said activation time point of said first vehicle control apparatus up to at least said activation time point of said second vehicle control apparatus.

8. In a vehicle control system, a first vehicle control apparatus comprising a communication circuit that is coupled for data communication with a second vehicle control apparatus, a storage medium for storing data received from said second vehicle control apparatus via said communication circuit, and control circuit means, said second vehicle control apparatus being changed from an inoperative condition to an operative condition at an activation time point that is delayed with respect to an activation time point of said first vehicle control apparatus at which the first control apparatus becomes changed from an inoperative condition to an operative condition,
wherein said control circuit means comprises: -
interval judgement means for judging whether a current time point is within a delay interval that extends from a time point of activation of said first vehicle control apparatus up to at least said activation time point of said second vehicle control apparatus, and inhibit means operating based on judgement results produced by said interval judgement means for inhibiting processing that utilizes data stored in said storage medium, during said delay interval; and wherein said first vehicle control apparatus implements respective functions of said interval judgement means and inhibit means by executing a program.

14. A method of controlling a vehicle comprising a first vehicle control apparatus and a second vehicle control apparatus, the first vehicle control apparatus having (i) a communication circuit that is coupled for data communication with the second vehicle control apparatus, and (ii) a storage medium for storing data received from said second vehicle control apparatus via said communication circuit, the method comprising:
-
changing the first vehicle control apparatus from an inoperative condition to an operative condition at a first activation time point of the first vehicle control apparatus; changing the second vehicle control apparatus from an inoperative condition to an operative condition at a second activation time point of the second vehicle control apparatus, the second activation time point being delayed with respect to the first activation time point; and inhibiting execution of processing that utilizes data stored in the storage medium of the first vehicle control apparatus during a delay interval extending from the first activation time point up to at least the second activation point. - View Dependent Claims (15, 16, 19, 20, 21, 22, 23, 24)

17. A method of controlling a vehicle comprising a first vehicle control apparatus and a second vehicle control apparatus, the first vehicle control apparatus having (i) a communication circuit that is coupled for data communication with the second vehicle control apparatus, and (ii) a storage medium for storing data received from said second vehicle control apparatus via said communication circuit, the method comprising:
-
changing the first vehicle control apparatus from an inoperative condition to an operative condition at a first activation time point of the first vehicle control apparatus; changing the second vehicle control apparatus from an inoperative condition to an operative condition at a second activation time point of the second vehicle control apparatus, the second activation time point being delayed with respect to the first activation time point; and inhibiting execution of processing that utilizes data stored in the storage medium of the first vehicle control apparatus during a delay interval; wherein the delay interval extends from the first activation time point to a time point at which data begins to be received from said second vehicle control apparatus via said communication circuit. - View Dependent Claims (18)
