A switch device includes a lid arranged between a tactile switch, which is arranged on a substrate, and an operation button, which is coupled to a retainer so that the operation button can be pushed. The lid includes an opening at a location corresponding to the tactile switch. A lower surface of the elastic member is coupled to a surface of the lid. The operation button, when pushed, activates the tactile switch with an elastic member. The operation body, when released from the pushed state, deactivates the tactile switch as a reaction force of the elastic member returns the operation button to an initial position. The switch device includes a projection that supports the operation button. The projection is formed on an upper surface of the elastic member at a location corresponding to the surface of the lid.

Switch device

A secret key registration system which registers a secret key in a portable key device and vehicle. A first transformation equation is stored in a writer and the vehicle. A second transformation equation is stored in the portable key device and the vehicle. The writer transmits a registration code to the portable key device and generates intermediate data with the first transformation equation of the writer. The intermediate data is transmitted to the portable key device, which generates the secret key from the intermediate data with the second transformation equation. The portable key device transmits the registration code to the vehicle. The vehicle generates intermediate data from the registration code with the first transformation equation of the vehicle, and then generates the secret key from the intermediate data with the second transformation equation.

System and method for registering secret key

A door unlocking device for a vehicle includes transmit/receive device activated to send an operation signal to a portable transceiver and receives an identification code from the transceiver, the transmit/receive device unlocking a door locking mechanism when the identification code matches a preset registration code, a starter switch activating the transmit/receive device when a door knob of an exterior door handle is pressed toward a vehicle body through first door handle actuation, and the door knob actuated to a first operation position and unlock unit unlocking the door locking mechanism when the door knob of the exterior door handle is actuated to a second operation position as a result of second door handle actuation subsequent to the first door handle actuation in the direction opposite to the direction of the first door handle actuation.

Door unlocking device for vehicle

An apparatus for controlling driving of a power window system having a motor drive current detection device for detecting a current flowing through the motor when the door glass is raised by the motor, a current variation calculation device for calculating a variation amount of the current detected by the motor drive current detection device, and a drive control device for stopping or reversing the motor when the variation-amount of the current exceeds a predetermined value and the gradient of the variation amount of the current is positive when the variation of the current starts. The apparatus can quickly and accurately judge whether an abnormal current is caused by noises or the squeeze of an alien substance, thereby eliminating unnecessary operations of the motor.
