A vehicle communication system includes a plurality of ECUs connected by the communication network including a plurality of communication transmission lines. Each of the ECUs includes an identification unit that identifies a target ECU to be a communication partner, and a relay transmission line and a relay ECU through which communication with the target ECU is routed, a standby time determination unit that determines a transmission standby time based on information on the relay ECU, the transmission standby time being a time from transmission of an activation instruction to another one of the ECUs closest to the ECU along the relay transmission line to transmission of a control signal toward the target ECU, and a communication unit that transmits the control signal after an elapse of the transmission standby time after transmitting the activation instruction to the relay transmission line closest to the ECU.

Vehicle communication system, vehicle communication method, and control device

A vehicle control system includes plural electronic control devices each of which controls an operation of a vehicle and which is mounted in the vehicle, a monitoring control device monitoring an operation of each electronic control device, and an electric connector which selectively sets an electronic connection of a power source line constantly performing a supply of power to a connection state or a non-connection state and which is provided between the power source line and each electronic control device, the monitoring control device includes a recording unit which performs a fault diagnosis of one electronic control device being a monitoring target and which executes a recording operation to store a diagnosis result in a storage device, and a mode setting unit setting the recording unit to a first operation mode executing the recording operation or a second operation mode not executing the recording operation.

Vehicle control system and vehicle control method

A vehicle drive assist system includes: an operation part that is operable from a neutral position to a first position at one side or a second position at another side; a switch part that outputs an ON signal or an OFF signal in accordance with a position of the operation part; a control part that generates a turn signal in response to an output of the switch part; a detection part that detects a rear side situation of a vehicle; and an alert part that performs an alert based on an output of the ON signal of the switch part and a detection result of the detection part, wherein in a case where an operation to the second position is performed when the turn signal in accordance with an operation to the first position is generated or in a case where an operation to the second position is performed after the turn signal in accordance with an operation to the first position is generated, a control that performs only a visual alert is performed.
