Abstract:
1. A driving assist system for assisting manual effort by an operator to operate an accelerator pedal of a motor vehicle, the driving assist system comprising: a data acquisition sub-system acquiring data including information on state of the motor vehicle and information on environment in a field around the motor vehicle; control logic for determining the degree of risk in the field around the motor vehicle in response to the acquired data; an actuator operable in response to a command for generating reaction force at the accelerator pedal; and control logic for simply increasing an increment of said reaction force between a first reaction force increment and a second reaction force increment as the determined degree of risk grows from a predetermined cutoff value to a predetermined critical value to determine the command for regulating the actuator to realize the increment in said reaction force, the first reaction force increment having a first magnitude in an area of a lower limit of a predetermined range, in magnitude, of increment in said reaction force, which the vehicle operator can perceive through the sense of touch during depressing the accelerator pedal, the second reaction force increment having a second magnitude in an area of an upper limit of the predetermined range.
