To provide a device for detecting whether heterogeneous tires are mounted on the respective left and right driving wheels or not and accurately detecting the decreased tire pressures. The detection device of heterogeneous tires of the present invention is equipped with a means for detecting the rotational speeds of wheels mounted on a vehicle, a means for detecting torque applied to driving wheels, and a calculation means for calculating the inclinations of regression straight lines of respective relations from relation between the rotational speed ratio of the front and rear wheels in the left side wheels of the vehicle and torque applied to driving wheels and relation between the rotational speed ratio of the front and rear wheels in the right side wheels of the vehicle and the torque, and detects that heterogeneous tires are mounted on the driving wheels by comparing the inclination of regression straight line of the relation of the left side wheels with the inclination of regression straight line of the relation of the right side wheels. The detection device of the decreased tire pressures of the present invention changes the threshold for judging tire deflation to a threshold in a case of loading heterogeneous tires when it detects that the heterogeneous tires are mounted on the driving wheels.

The invention discloses a redundant driving electric brake of an airplane and a control method for the redundant driving electric brake. A redundant driving controller part receives a brake pressure given signal and drives a brake actuator to work, so that brake pressure applied to a braked wheel follows the brake pressure given signal. By adopting a redundant technology, easily damaged mechanisms in an airplane brake driving device are subjected to warm backup; under the condition of normal working, the corresponding parts work at half of rated power, so that the service life of the driving device is prolonged, and the reliability of the driving device is improved; when certain redundancy of the driving device fails, a failure can be detected in real time and isolated, so that a fault motor quits a working state, and the driving device runs after being switched to a single-channel mode; and therefore, the reliability of a braking system of an airplane is improved.

The invention discloses a dual-redundancy electric brake device of an airplane and a control method for the dual-redundancy electric brake device. A redundant driving controller part receives a brake pressure given signal and drives a brake actuator to work, so that brake pressure applied to a braked wheel follows the brake pressure given signal. By adopting a redundant technology, easily damaged mechanisms in an airplane brake driving device are subjected to warm backup; under the condition of normal working, the corresponding parts work at half of rated power, so that the service life of the driving device is prolonged, and the reliability of the driving device is improved; when certain redundancy of the driving device fails, a fault can be detected in real time and isolated, so that a fault motor quits a working state, and the driving device runs after being switched to a single-channel mode; and therefore, the reliability of a braking system of an airplane is improved.
