Abstract:
According to an embodiment of the present invention, a door driver module includes: an integrated circuit on which devices for operation of a door are integrated; a micro-controller (MCU) which is provided to be separated from the integrated circuit and provides the integrated circuit with commands; a controller area network (CAN) transceiver which is for the communications of the MCU; and a serial-parallel interface (SPI) which is for the communications between the integrated circuit and the MCU.
Abstract:
PURPOSE: A system for reducing speed and detecting a speed bump is provided to detect the speed bump and to calculate decelerating point in advance for smoothly passing over the speed bump. CONSTITUTION: A system for reducing speed and detecting a speed bump consists of a sensing part(110), a control part(130), a decelerating part(150), and a storage part(140). The sensing part detects a front speed bump and calculates a decelerating point. The control part calculates a decelerating speed from the decelerating point to the speed bump and controls an airbag apparatus according to the calculation result by judging the calculated decelerating speed is a preset standard value or more. The decelerating part decelerates the vehicle speed according to the decelerating speed. The storage part stores the preset standard value for decelerating.
