  • Patent number: 12162428
    Abstract: The disclosure provides a vehicle control system (VCS) capable of safely and forcibly controlling a vehicle. The VCS includes a mode setting unit configured to output a forced mode signal upon receiving a forced control instruction from outside the vehicle via a communication device, and a forced operation unit configured to output a forced operation signal of forcibly operating vehicle to an operation control unit. Further, the VCS includes a signal selection unit configured to allow all the operation signals to pass therethrough before receiving the forced mode signal, and block at least a part of the operation signals and allow the forced operation signal instead of the blocked operation signal to pass therethrough after receiving the forced mode signal. The VCS controls an operation of the vehicle by controlling the operation control unit based on the operation signal or the forced operation signal passing through the signal selection unit.
