摘要: When it is confirmed that a user exists based on an image of the situation outside a vehicle which is captured using a camera and a proximity sensor detects a fact that the user is approaching based on, for example, a putting of a hand of the user over the proximity sensor, a control device causes a ramp to be extended. As such, a user sitting in a wheelchair can cause the ramp to be extended by approaching the proximity sensor, such as the putting of the user's hand over the proximity sensor such that the user sitting in the wheelchair does not have to press an extension/storage button provided on the vehicle to cause the ramp to be extended.

摘要: A power converter for an electric vehicle that converts output of a battery to driving an electric traction motor is disclosed. The power converter may include: a power switching element; a current sensor provided on a bus bar in which an output current of the switching element flows; a cooler cooling the switching element; a temperature sensor measuring a temperature of a coolant; and a controller controlling the switching element. The controller may be configured to: estimate a temperature of the current sensor based on the temperature of the coolant; determine a first and second correction values for the estimated temperature based on the output current and an input voltage applied to the switching element; and restrict a load on the switching element when a corrected temperature, which is obtained by adding the first and second correction values to the estimated temperature, exceeds a predetermined temperature threshold.

摘要: This on-vehicle communication device includes: a storage unit configured to store correspondence information indicating a correspondence relationship between an address and a port number; and a communication unit configured to perform, by using the correspondence information, filtering of a packet having been received. A target port number which is a port number of a target instrument is registered in advance in the correspondence information. In the filtering, the communication unit selectively allows a packet that includes the target port number, to pass. The communication unit performs an address registration process of acquiring an address from the packet that includes the target port number and registering, into the correspondence information, the acquired address in association with the target port number. In the filtering after the address registration process, the communication unit selectively allows a packet that includes the target port number and the corresponding address, to pass.

摘要: An electric vehicle includes a main battery, a power converter, a relay, and a controller. The power converter is a device that converts power of the main battery to drive electric power for a motor. The power converter includes a voltage sensor that measures an input voltage. The relay is connected between the main battery and the power converter. The controller stores an output value of the voltage sensor as an offset value at time after a vehicle main switch is turned on and before the relay is closed. The controller controls the power converter based on a value acquired by subtracting the offset value from the output value of the voltage sensor after the relay is closed. The controller opens the relay when a value acquired by subtracting the offset value from the travel-time output value exceeds a first voltage threshold.
