Abstract
In a vehicular control apparatus, a minimum operating voltage of a first characteristic device is set to be lower than a minimum operating voltage of a second characteristic device. A supply voltage controller is provided between a controller and the second characteristic device to prevent an occurrence of a situation where a supply voltage of a device power supplied to the second characteristic device becomes less than an input voltage of a signal line of a control signal transmitted from the controller to the second characteristic device.
Claims7
A vehicular control apparatus, comprising:
- a first characteristic device configured to provide a function of a first characteristic;
- a second characteristic device configured to provide a function of a second characteristic;
- a controller configured to output a control signal to each of the first characteristic device and the second characteristic device via a signal line;
- and
- a supply voltage controller provided between the controller and the second characteristic device,
- wherein:
- a minimum operating voltage of the first characteristic device is set to be lower than a minimum operating voltage of the second characteristic device;
- and
- the supply voltage controller is configured to prevent an occurrence of a situation where a supply voltage of a device power supplied to the second characteristic device becomes less than an input voltage of the signal line of the control signal transmitted from the controller to the second characteristic device.
