摘要:
An engine electronic control unit is inserted through a through hole provided in an intake pipe and mounted in an intake air passage in a direction substantially perpendicularly with respect to a plane of the intake pipe forming the intake air passage. This unit is then secured to the intake pipe using a fixing flange provided at a connector portion. A fixing rail is protruded inside the intake pipe and leading edges of a metal base and a metal cover of the unit are inserted into this rail, thereby securing in position an end opposite to a side of the connector portion of the unit. This realizes an engine electronic control unit offering an outstanding heat radiation performance and vibration resistance, without having to provide special heat radiating parts or without involving an increase in an intake air resistance within the intake air passage. By using such an engine electronic control unit, it is possible to provide a low-cost, compact engine air intake system.

摘要:
An air flow meter which can decrease the error due to the backflow. Throttle valve 17 which opens and shuts the air intake passage is installed in the air intake passage of the internal combustion engine. The first sensor part 161 is installed in the air intake passage in the upstream of throttle valve 17. Further, the second sensor part 141 is installed in the air intake passage in the downstream of throttle valve 17. Pulsation compensating means 671 corrects the pulsation of the air flow rate signal detected by the first sensor part by using the output signals of the first and the second sensor parts 161, 141 based on each cylinder of the internal combustion engine.
摘要:
A low-cost vehicle control system and a car using the system controls radiation of an actuator driver and thereby reduces the radiation component cost and allows downsizing of an electronic control unit to improve the versatility. The vehicle control system has an electronic control unit, a plurality of actuators and actuator drivers for driving the actuators at the actuator side. The actuator drivers, respectively, have an independent self-diagnosis section, a self-protection section, and a communication control section and are dispersed correspondingly to the actuators.
