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 a independent self-diagnosis section, a self-protection section, and a communication control section and are dispersed correspondingly to the actuators.

Provided is a brushless-motor fan unit having a centrifugal fan and a scroll casing enclosing the centrifugal fan therein. The rotor of the brushless-motor is carried by the centrifugal fan. Further, the motor shaft carrying the centrifugal fan is supported at its front and rear ends by the scroll casing. With this construction, the motor housing can be eliminated so as to obtain a compact centrifugal type motor fan unit in a small thickness as a whole.

摘要:
An electric motor fan comprises a fan driven by a motor, a case with the fan mounted therein and including a scroll providing an air outlet port of the fan, and a control unit including an output transistor for controlling the drive of the motor. The control unit includes a heat radiation device mounted in the scroll for radiating the heat generated by the transistor. At least a part of the heat radiation device is formed as a radiation fin having an internal surface in the same plane as the internal wall surface of the scroll.

摘要:
A control apparatus for controlling multiple power loads in a vehicle includes a circuit for detecting a current abnormality of a power element and a circuit for monitoring a temperature abnormality in a locality of the power element. Circuits are also provided continuing or shutting down the power element based on information concerning the above stated current and/or temperature abnormalities, with a timing which is established according to a substantially constant period or a time interval which is stored in advance in a memory element.
摘要:
In a temperature control unit for a vehicular air conditioning unit including a blast unit and control for the blowoff temperature thereof, a control circuit is provided with a variable gain so that the gain is increased when the blast unit blows air with a high velocity and is decreased when the blast unit blows air with a low velocity whereby a temperature control which does not cause discomfort to a human body may be carried out promptly and automatically. The variable gain of the control circuit may be provided in the form of a feedback loop of the control circuit with at least one of variable resistance or capacitance so as to vary the time constant of the feedback loop and therewith the gain in accordance with the air velocity.
