Electronic force controlling type automobile pair braking device

The utility model discloses an electronic force controlling type automobile pair braking device which comprises an auxiliary braking pedal (14) at a co-driver chassis, a single chip microcomputer (1), a traction electromagnet (5) and a relay (4). The periphery of the single chip microcomputer (1) is provided with a power supply (11), a vehicle speed sensor (2) and an auxiliary brake pedal switch (3), wherein the power supply (11), the vehicle speed sensor (2) are connected with the single chip microcomputer (1), and the auxiliary braking pedal switch (3) is linked with the auxiliary braking pedal (14). The vehicle speed sensor (2) and the auxiliary braking pedal switch (3) are respectively connected with the power supply (11) to form an input signal of the single chip microcomputer (1). The output of the single chip microcomputer (1) is amplified by a power amplifier and then drives the traction electromagnet (5). An armature (6) in the traction electromagnet (5) is used for driving an automobile main braking
