Provided is a wheel load estimation device configured to acquire wheel speed information of each wheel included in a vehicle from a wheel speed sensor provided in the vehicle; to calculate a front-rear load ratio and a left-right load ratio based on the wheel speed information; and to calculate a wheel load ratio expressing a relative wheel load between the wheels included in the vehicle, with respect to at least one wheel of the vehicle, based on the front-rear load ratio and the left-right load ratio. The front-rear load ratio is a ratio between a load applied to a front wheel of the vehicle and a load applied to a rear wheel of the vehicle, and the left-right load ratio is a ratio between a load applied to a left wheel of the vehicle and a load applied to a right wheel of the vehicle.

An advance driver brake customizing method applied to a brake customizing system is provided to identically implement a braking feeling set according to a driver's vehicle regardless of a vehicle type by transplanting driver braking feeling information of a driver's vehicle into a braking feeling matching vehicle. A braking characteristic of a brake of a brake system, which is applied to the braking feeling matching vehicle, is directed to follow the braking characteristic of a brake of the brake system, which is applied to the braking feeling matching vehicle, through driver matching control in conjunction with a wireless network. In particular, even when the same driver changes a vehicle or a driver for the same vehicle is changed, the same braking feeling is maintained.

A method monitors a condition of a mechanical brake of an aircraft. In the method, a temperature of the mechanical brake is measured at at least one point in time during a landing operation after commencement of a mechanical braking operation. The measured temperature is compared with a standard temperature determined for the mechanical brake, at the at least one point in time during the landing operation after commencement of the mechanical braking operation. A state of wear of the mechanical brake is then identified on the basis of the measured temperature having exceeded the standard temperature beyond a predefined measure.
