A main control portion of a vehicle has an LF transmission antenna for transmitting a search signal. The LF transmission antenna has five antennas respectively provided on door knobs of the vehicle. A smart key receives the search signals transmitted from respective antennas constituting the LF transmission antenna, and then measures a filed strength of the received search signal. The smart key transmits field strength information representing the measured field strength to the main control portion. The main control portion calculates relative position information of the vehicle to the smart key, based on the field strength information. On the basis of the relative position information, the main control portion controls the door of the vehicle to be locked or unlocked.

Vehicle control system and vehicle control apparatus

A remote vehicle starter allows a user to start an engine of a vehicle remotely. The starter includes a parameter-signal generating unit, a receiving unit, an engine starting unit and a controller. The parameter-signal generating unit generates a vehicle-parameter signal on a basis of a power source. The receiving unit receives an instruction for starting the engine. The engine starting unit starts the engine when receives the instruction for starting the engine from the receiving unit and receiving the vehicle-parameter signal satisfying a starting permission condition from the parameter-signal generating unit. The controller controls an engine starting by the engine starting unit, in accordance with a power source voltage value of the power source.

Remote vehicle starter and method for remotely starting vehicle

A vehicle remote starting apparatus includes a control device that starts an engine when the control device has set a registration flag and the control device receives an engine starting signal from an external device, which is apart from the vehicle remote starting apparatus. When the vehicle remote starting apparatus is mounted on a vehicle, the control device executes registration process for setting the registration flag, which allows the control device to start the engine when the control device receives the engine starting signal.

Vehicle remote starting apparatus and method for executing registration process

A remote start-up control apparatus which takes in a key code outputted on the basis of insertion of a key cylinder of an ignition key, and which is mounted on a vehicle which was equipped with an immobilizer unit for enabling a start-up of an engine, in case that it was judged that the taken-in key code is in conformity with a predetermined key code, and which carries out start-up control of an engine in response to an instruction of a portable transmitter, has a unit for supplying a key code which has been stored in an EEPROM to the immobilizer, when it received a start-up instruction of the engine according to a remote operation, and a unit for prohibiting supply of the key code, in case that there occurred vehicle theft.
