A control unit indicates a cursor on a screen of an indication unit according to operation data sent from an operation unit based on user's operation of an operation knob. The control unit implements enlarging indication of a screen region corresponding to a selection item image indicated on the screen of the indication unit. When the control unit implements contracting indication to return an enlarged screen region subsequent to the enlarging indication, the control unit indicates contraction of the screen region in a visually recognizable form and indicates the cursor to follow the screen region. The operation unit further causes a driving force generation unit to generate a driving force to move the operation knob correspondingly to the position of the cursor, according to information on the position of the cursor sent from the control unit.

Vehicular device

A portable terminal receives a user operation on a terminal screen of the portable terminal in a portable terminal normal mode. After receiving the user operation, the portable terminal shifts from a portable terminal normal mode to a portable terminal in-operation state, in which the portable terminal sends out a portable terminal in-operation notice to an in-vehicle apparatus. The in-vehicle apparatus shifts to a portable terminal in-operation mode upon receiving the notice from the portable terminal, and invalidates a reaction force by a reaction force generation unit to transit to a portable terminal normal state.

Operation support system, in-vehicle apparatus and portable terminal

A door lock control apparatus includes a lock switch on an exterior of a vehicle, a controller, and a check device. The controller performs a first key check in response to a lock command inputted through the lock switch. The first key check determines whether an electronic key specific to the vehicle is located outside around the vehicle based on a response from the key. The check device has previously performed a second key check, after the key has been put into a situation in which the key might have been moved from inside to outside the vehicle. The second key check determines whether the key is located inside the vehicle based on the response from the key. The check device stores a result of the second key check as a stored check record, which is then immediately available for checking when the controller responds to an inputted lock command.

Door lock control apparatus for vehicle

A smart entry system includes a vehicle-side unit and a plurality of portable devices. Each of the portable devices has a discrimination code different from each other. When a first portable device is locked in a vehicle compartment, the discrimination code of the first portable device is stored in the vehicle-side unit. When the vehicle is parked in a state where all of the doors are locked, the vehicle-side unit transmits a request signal to an exterior communication area provided at an outside of the vehicle, and when the vehicle-side unit receives a response signal from a second portable device and the discrimination code of the second portable device is different from the discrimination code of the first portable device stored in the vehicle-side unit, the vehicle-side unit permits an unlock of the doors of the vehicle.
