Exhaust gas diagnosis system and vehicle control system
First Claim
1. A vehicle control system comprising:
- a vehicle control unit to control a vehicle component device;
radio terminal units each having a sensor to monitor the vehicle conditions; and
a radio communication repeater to receive, by radio communication, the vehicle conditions detected by the sensor of the radio terminal units;
wherein the radio communication repeater includes a memory having stored therein a program to determine the vehicle conditions; and
wherein the radio communication repeater, upon receipt of a start signal from-the vehicle control unit, executes the program and outputs the result of determination of the vehicle conditions.

Abstract
An exhaust gas diagnosis system and a vehicle control system for automotive vehicles to reduce the communication lines and the power lines connected to the antiweatherability-required exhaust gas sensor arranged on the exterior of the vehicle are disclosed. The exhaust gas diagnosis system is configured of an engine control unit (electronic control unit), radio terminal units having the sensor function to detect the exhaust gas, and a radio communication repeater to conduct communication and share a part of the process executed by the conventional engine control unit. The communication lines between the sensor and the electronic control unit and the power lines to the sensor required in the conventional systems are eliminated while at the same time reducing the load on the electronic control unit.

12. A vehicle control system comprising:
-
a vehicle control unit to control a vehicle component device;
radio terminal units each having at least a sensor to monitor a vehicle component part;
a first radio communication repeater to receive, by radio communication, the conditions of the vehicle component part detected by the sensor of the radio terminal units; and
a vehicle overall control unit connected with the first radio communication repeater;
wherein the first radio communication repeater includes a memory having stored therein a program to determine the conditions of-the vehicle component part;
wherein the first radio communication repeater executes the program to monitor the conditions of the vehicle component part, and upon detection of a predetermined change in the vehicle component part, outputs the result of determination of the conditions of the vehicle component part to the vehicle overall control unit; and
wherein the vehicle overall control unit (5010) transmits the first control information corresponding to the predetermined change in the vehicle component part received to the vehicle control unit. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)
