Title:
AUTOMOBILE CONTROL SYSTEM
Document Type and Number:
Japanese Patent JPH1127300
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an automobile control system that can surely perform an A/D conversion and a highly reliable automobile control by giving a degree of freedom to a conversion timing of the A/D conversion. SOLUTION: A multiple communication circuit 1000 transmits a detection signal of an analog sensor SEN (SEN0 to SEN7) to a data bus DB, while a control device 2000 generates a control signal for controlling an automobile on the basis of the detected signal transmitted by way of the data bus DB and sends the generated control signal to an actuator ACT by way of the data bus DB and the multiple communication circuit 1000. The multiple communication circuit 2000 has a sample hold circuit 1100 for sampling and holding the detected signal of the analog sensor SEN, a multiplexer circuit 1200 for selecting an output signal of a sample hold circuit 1100, and a logical circuit 1400 for setting a sampling timing in the sample hold circuit 1100. The sampling timing D- SH which the logical circuit 1400 sets is temporally displaced and set within the range of a fixed time including specific cycle of time.
