An automotive driving instruction system which comprises a plurality of sensors including a vehicle speed sensor etc. mounted at various parts of the automobile, a computer for reading the outputs of the sensors for calculating the driving conditions of the automobile, and a replaceable external memory unit. The computer calculates a plurality of values representing the driving conditions of the automobile on the basis of the outputs of the sensors, and controls to generate an alarm when any of the values thus calculated becomes to corresponding one of a plurality of predetermined values. Also, the accumulated value of the alarms and the respective accumulated values of the alarms for each of causes of alarming are stored in the external memory unit. At the end of a driving, the external memory unit is demounted, so that any habits of the driver is determined from the data stored in the external memory unit to contribute to the correction thereof.

Automotive driving instruction system

A vehicle driver's seat is equipped with an electromagnetically operated vibrator arranged in its back-rest to be activated by energization of an electric control circuit for periodically supplying an electric current to the vibrator from a vehicle battery. A safety device for the driver's seat comprises a parking brake switch arranged between the electric control circuit and the battery to be opened during the inoperative condition of a parking brake of the vehicle and to be closed in response to operation of the parking brake, and an additional control circuit for energizing the electric control circuit in response to closing of the switch to activate the vibrator during arrest of the vehicle and for deenergizing the electric control circuit in response to opening of the switch to deactivate the vibrator during movement of the vehicle.
