PURPOSE: To correctly determine a road adhesion, and realize ABS control of high reliability by providing means to measure a steering angle, car speed, and steering force, and calculating a signal expressing the size of the road adhesion based on output signals of the three measuring means. CONSTITUTION: This automotive device controls a driver alarm device 40, a brake controller 42, and an acceleration controller 44 by a control module 16 receiving input of output signals of a car speed sensor 22, a steering angle sensor 24, and a steering force sensor 26. In this case, in the control module 16, measurement values of a steering angleα, car speed V, and steering force Fs are compared with reference three elements in a ROM having specified valuesα, V, Fs. When the valuesα, V, Fs are included in reference specified values, a road adhesion value corresponding to the reference values of the three elements is read from the ROM. Next, if the road adhesion value is less than an initial value or not is determined, and for YES, an output control command is generated to actuate an emergency control device.
