摘要： A driving assistance apparatus mounted to a vehicle is disclosed. The apparatus determines whether an amount of change in tire wheel speed of each tire wheel of the vehicle exceeds a threshold. The apparatus specifies a tire wheel crossing order, which is an order in which the tire wheels of the vehicle cross over a level difference between a road and a parking lot when the vehicle crosses over the level difference. The apparatus determines whether or not the vehicle has crossed over the level difference between the road and the parking lot, based on whether a threshold-exceeding order is identical to the specified tire wheel crossing order. The threshold-exceeding order is an order in which the amounts of change in the tire wheel speed of the respective tire wheels exceed the threshold.

摘要： A signal transmission circuit is capable of reducing distortion that occurs during signal transmission. A digital output signal is transmitted from a terminal to a signal line via an output buffer circuit and an output impedance unit. The terminal is connected to an impedance variation unit via an impedance control unit. The impedance variation unit designates an impedance for terminating the signal line when the output data is changed from a high level H to a low level. A reflection occurring on the signal line can be prevented and a waveform distortion can be suppressed.

摘要： A drive-assist information providing system is installed beforehand in a vehicle. The system provides drive-assist information to the driver when the vehicle is running, or temporarily halting, on one lane of a road within a predetermined assist zone. The system includes a first obtaining unit for obtaining a current position and behavior of the vehicle, and a second obtaining unit for obtaining a current position and behavior of an object around the vehicle. The system includes an identifying unit for identifying current circumstances of the vehicle and therearound based on the current position and behavior of the vehicle and on the current position and behavior of the object around the vehicle. The system includes a control unit for controlling how to provide the drive-assist information to the driver of the vehicle depending on the identified current circumstances of the vehicle and therearound.
