A vehicle control device is configured to determine whether or not a living body is left behind in a vehicle. The vehicle control device includes an operation information acquisition unit that acquires first operation information indicating whether a first type of opening/closing unit related to getting-on/off of an occupant is operated and second operation information indicating whether a second type of opening/closing unit other than the first opening/closing unit is operated; a leaving determination unit that determines whether the living body is left behind with reference to the first operation information, and determines execution of a leaving alarm in a case where it is determined that the living body is left behind; and an execution holding unit which holds the execution of the leaving alarm in a case where the second operation information indicates that the second type of opening/closing unit is operated.

Vehicle control device and vehicle control method

A vehicle door opening and closing control device opens or closes a door of a vehicle according to a kicking motion of a leg detected by a kick sensor. A threshold is set for output from the kick sensor. Motion duration time until the output from the sensor falls below the threshold after the output from the sensor exceeds the threshold in a kicking motion is measured. Motion completion estimated time until the kicking motion is completed is calculated according to the motion duration time, for example, by assuming that motion completion estimated time=motion duration time/2. When the elapsed time after the output from the sensor falls below the threshold reaches the motion completion estimated time, opening operation or closing operation of the door starts.

A detector includes a plurality of sensors and is configured to detect a user in preliminarily set detection areas. The sensors are arrayed horizontally at a rear portion of a vehicle such that the detection areas of the adjacent sensors overlap with each other. If any one of the sensors detects the user and outputs a detection signal (first detection signal), a threshold for a detection signal of one of the sensors adjacent to the sensor (second detection signal) is raised and the first and second detection signals are converted to first and second binary signals, respectively. A rear door is opened if the second binary signal has an output period that is contained in an output period of the first binary signal.

Vehicle door open-close control device

An electric power is surely supplied to a load even if an abnormality is generated in a switching control circuit, which controls a switching part that switches electric connection between a power supply and the load of a vehicle. The switching control circuit controls a state of a contact of a keep relay that switches the electric connection between the power supply and the load. A monitor circuit monitors existence or non-existence of the abnormality of the switching control circuit. When detecting the abnormality of the switching control circuit, the monitor circuit transmits a reset signal in order to reset a state of the switching control circuit. When receiving the reset signal from the monitor circuit, an abnormal-time connection circuit transmits a connection signal to a coil of the keep relay to bring a movable contact into contact with a contact. For example, the present invention can be applied to a power-supply control device for the vehicle.

Power-supply control device

An in-vehicle instrument control device, that controls a power source of a plurality of in-vehicle instruments operated by power from the power source provided in a vehicle, includes a plurality of operation units to operate the respective in-vehicle instruments; and a plurality of power source control units that are each provided between the operation unit and the power source, and the in-vehicle instrument, and each supply the power from the power source to the in-vehicle instrument when a predetermined operation signal is inputted from the operation unit.

In a headlamp luminance controlling device, a CPUfirst decides a luminance factor D based on a state of each switchto switchand a signal from a sensor. The CPUdetermines an initial value of a PWM duty ratio S from the luminance factor D with a load current Ap as a default value (rated current A). The CPUstarts the initial driving of a headlamp HL using the duty ratio S. The CPUthen determines the luminance factor D based on the state of each switchto switchand the signal from the sensor. Next, the CPUdetermines the PWM duty ratio S based on the luminance factor D and the load current Ap detected by the headlamp current detector. The CPUdrives the headlamp HL using the PWM duty ratio S.

Lighting control device and control method

In an illumination control apparatus which drives headlamps in a PWM mode and automatically lights them at low power in a vehicle when the DRL executing condition is held, failure in a PWM-drive switching device and break failure in the lamp are detected as well as the arrangement of control units is optimized and meeting models is facilitated. A relay which switches between lamps and a power source, a CPU which is connected to a CAN and drive-controls the relay for manual lighting, and an integrator circuit which integrates voltage of drive side terminals of the lamps are disposed in a main control unit. An FET which switches between the lamps and the power source, a CPU which drive-controls the FET for automatic lighting, and a power source connecting resister having a resistance value greater enough than that of the lamp that drive side terminals of the lamps are connected to the power source through an ignition switch contact of the vehicle are disposed in a DRL control unit. The CPU determines failure based on the output voltage of the integrator circuit.
