摘要:
A failure detection device and method for an oil temperature sensor that detects an oil temperature of hydraulic fluid of an automatic transmission mounted in a vehicle. It is determined that a failure has occurred in the oil temperature sensor if the oil temperature, which is detected by the oil temperature sensor when a predetermined elapsed-time has elapsed since an engine of the vehicle is started, is not within a predetermined temperature range. The predetermined elapsed-time is variably set based on the oil temperature that is obtained when the engine of the vehicle is started.
摘要:
Presented is an EDR for storing predetermined information. The EDR is mounted to a vehicle (e.g., automobile) and includes a control unit that determines an event and controls a storage unit to store predetermined information therein. If the driver either depresses an accelerator pedal within a predetermined period after manipulating a shift lever or simultaneously manipulates the shift lever and depresses the accelerator pedal, the storage unit is controlled to store therein at least operating information on the operation of the shift lever and the accelerator pedal and traveling state information on the vehicle's traveling state. This configuration limits unnecessary increases in size of stored data even if information is stored on events that are not directly related to accidents.
