Abstract
An electromagnetic brake pedal feel simulation system may simulate the feel of a manual brake pedal when force is applied to a power-assist brake pedal mounted to an arm. The electromagnetic brake pedal feel simulation system may include an electromagnetic movement resistance device. The device may mechanically couple to the power-assist brake pedal pad or arm and may apply a controllable amount of force against a braking force that is applied to a power-assist brake pedal pad that is a function of the amount of a drive signal current. The electromagnetic movement resistance device may include a pair of magnets having both of their north or south poles facing each other and that come closer together as force is applied to the power-assist brake pedal pad. At least one of the magnets may be an electromagnetic to which the drive signal current may be applied. The electromagnetic brake pedal feel simulation system may include a brake pedal position sensor that senses the position of the power-assist brake pedal pad or arm. A controller may be electrically connected to at least one electromagnet and to the brake pedal position sensor. The controller may cause the amount of the drive signal current to vary based on the position of the power-assist brake pedal pad or arm, as sensed by the sensor.
