PROBLEM TO BE SOLVED: To provide a vehicle control system etc. which can limit or inhibit actuation of on-board units properly based on field-strength of RF signals being received from a portable device to a communication apparatus of a vehicle, when the on-board units are made to actuate based on two way communication between the vehicle and the portable device.SOLUTION: A vehicle comprises: a LF transmitting section which transmits predetermined first signals in a predetermined region of vehicle outdoor; a RF receiving section which receives predetermined second signals and third signals from a portable device; a detection section which detects field-strength of signals received by a LF receiving section; a control section which actuates on-board units based on receiving of the third signals; and a limit section which limits and inhibits actuation of the on-board units based on the third signals when field-strength of the third signals is less than field-strength of the second signals beyond a predetermined standard. The portable device comprises: the LF receiving section which receives the first signals from the vehicle; and a RF transmitting section which transmits the third signals to the vehicle after the second signals to the vehicle in a case of receiving of the first signals.SELECTED DRAWING: Figure 3A
【課題】車両と携帯機との間での双方向通信に基づき、車載装置を作動させる場合に、車両の通信機が携帯機から受信するRF信号の電波強度に基づき、適切に車載装置の作動を制限或いは禁止することが可能な車両制御システム等を提供すること。【解決手段】車両は、車室外の所定範囲内に所定の第1信号を送信するLF送信部と、携帯機から所定の第2信号及び第3信号を受信するRF受信部と、LF受信部が受信した信号の電波強度を検出する検出部と、第3信号の受信に基づき、車載装置を作動させる制御部と、第3信号の電波強度が、第2信号の電波強度よりも所定基準を超えて小さい場合、第3信号に基づく車載装置の作動を制限又は禁止する制限部と、を備え、携帯機は、車両からの第1信号を受信するLF受信部と、第1信号を受信した場合、車両に第2信号を送信し、その後、車両に第3信号を送信するRF送信部と、を備える。【選択図】図3A
