Abstract
A vehicular lamp apparatus includes: a lamp unit; a controller that controls the lamp unit based on vehicle information received from a vehicle; and an acceleration sensor that provides information indicating vehicle acceleration to the controller. The controller detects whether or not reception of the vehicle information is interrupted and controls the lamp unit based on the vehicle acceleration when interruption in the reception of the vehicle information is detected.
Claims6
A vehicular lamp apparatus, comprising:
- a lamp unit;
- a controller that controls the lamp unit based on vehicle information received from a vehicle controller;
- and
- an acceleration sensor that provides information indicating vehicle acceleration to the controller,
- wherein the controller detects whether or not reception of the vehicle information is interrupted and controls the lamp unit based on the vehicle acceleration when interruption in the reception of the vehicle information is detected, and
- wherein the controller is structured to detect whether the reception of the vehicle information is restored while controlling the lamp unit based on the vehicle acceleration, and to return control of the lamp unit to being based on the vehicle information when the reception of the vehicle information is restored.
A control device for a vehicular lamp apparatus, the control device comprising:
- an Electronic Control Unit (ECU) that controls a lamp unit based on vehicle information received from a vehicle controller;
- and
- an acceleration sensor that provides information indicating vehicle acceleration to the ECU,
- wherein the ECU detects whether or not reception of the vehicle information is interrupted and controls the lamp unit based on the vehicle acceleration when interruption in the reception of the vehicle information is detected, and
- wherein the ECU is structured to detect whether the reception of the vehicle information is restored while controlling the lamp unit based on the vehicle acceleration, and to return control of the lamp unit to being based on the vehicle information when the reception of the vehicle information is restored.
A control method for a vehicular lamp apparatus, the control method comprising:
- detecting whether or not reception of vehicle information for use in control of a lamp unit is interrupted;
- acquiring information indicating vehicle acceleration from an acceleration sensor;
- controlling the lamp unit based on the vehicle acceleration when interruption in the reception of the vehicle information is detected,
- detecting whether the reception of the vehicle information is restored while controlling the lamp unit based on the vehicle acceleration, and
- returning control of the lamp unit to being based on the vehicle information when the reception of the vehicle information is restored.
