摘要： A motor vehicle is provided with a driving status discrimination device, which includes a detector for detecting a parameter signal (e.g., vehicle speed, engine rotational speed, the opening degree of an engine throttle valve, or the like) relating to the driving speed of the motor vehicle at a predetermined interval, and a microcomputer for processing the parameter signals input thereto. The microprocessor calculates a differentiated value of the parameter signal and stores the differential value in a memory device. The memory device has a plurality of memory locations each storing the differential value. The microprocessor futher calculates an integrated value of a plurality of differentiated values stored in the memory device and discriminates various driving status from one another (e.g., a mountain road driving from a high speed driving) based upon the calculated integrated value.

摘要： A driving status discrimination device for a motor vehicle is provided with a microcomputer, which stores in a memory a plurality of the latest steering angle signals which are output from a steering angle detector each time the vehicle runs a predetermined distance. The microcomputer processes the steering angle signals stored in the memory to calculate a discrimination value and then, compares the discrimination value with a predetermined reference value, so that the driving state of the vehicle can be judged to be either of a mountain road driving and a town street driving. To calculate the discrimination value, the microcomputer in one embodiment searches said memory for some of the steering angle signals whose values belong to a particular one of classification intervals and calculates the ratio of said searched steering angle signals to all of the steering angle signals stored in the memory. Also to calculate the discrimination value, the microcomputer in another embodiment calculates a mean value of absolute values of the steering angle signals stored in the memory.
