A method of taxiing an aircraft may comprise determining, via a controller, whether the aircraft is taxiing with fewer brakes active than a total number of brakes; and modifying, via the controller, a brake pressure supplied to an active brake of the aircraft as a function of pedal deflection in response to determining the aircraft is taxiing with fewer brakes active relative to the total number of brakes.

A pedal assembly includes a housing, a spring arm member, a pedal arm, a spring carrier, and a spring guide member. The spring arm member is coupled to the housing. The pedal arm has a hub portion and an opposite pedal pad. The hub portion is pivotally retained in the housing by the spring arm member at the hub portion. The spring carrier is coupled to the pedal arm and to the spring arm member. The spring carrier has at least one spring positioned to provide a first pedal effort force to the pedal arm at a first amount of predetermined travel of the pedal arm. The spring guide member contacts a second at least one spring from the pedal arm when the pedal arm exceeds a second amount of predetermined travel of the pedal pad. The at least one spring provides a second pedal effort force.

A method for detecting a resistance on a brake pedal of a brake system, in which a brake pedal is pulled by an actuator, in which an ease of movement of the brake pedal is determined during operation of the actuator, wherein a resistance is detected as soon as the ease of movement is no longer clearly determined, and a method for controlling an actuator, a computer program product, control unit or system comprising a plurality of control units, and a corresponding device.

A brake system capable of accurately controlling a braking force includes a first and second brake devices that have different control accuracies, and a brake control device that controls a braking force of the first and second braking devices according to a required braking force. The brake control device has a first control mode in which the braking force of the first brake device is controlled to be smaller than the braking force of the second brake device, and a second control mode in which the braking force of the first brake device is increased rather than the first control mode. The second brake device is controlled so that a sum of the braking force of the first brake device and the braking force of the second brake device matches the required braking force.

A vehicle control apparatus includes a generator, a brake system, first and second sensors, first and second deceleration rate setting units, and a power generation torque controller. The first deceleration rate setting unit sets, when a first control mode that decelerates a vehicle on the basis of a brake operation performed by an occupant is executed, an allowable deceleration rate upon deceleration of the vehicle on the basis of a brake operation amount. The second deceleration rate setting unit sets, when a second control mode that decelerates the vehicle on the basis of a situation ahead of the vehicle is executed, the allowable deceleration rate upon deceleration of the vehicle on the basis of a brake fluid pressure. The power generation torque controller controls power generation torque of the generator on the basis of the allowable deceleration rate that is set by the first or second deceleration rate setting unit.

Multiple sensors are coupled to a first pin of a PSI5 transceiver to receive a sensor bus signal. A Manchester decoder is coupled to a second pin and a battery is coupled to a third pin. A comparator receives a first voltage that is proportional to a current on the sensor bus signal and a second voltage that is proportional to a base current on the sensor bus signal and sends a data output signal to the second pin. A sample-and-hold circuit captures a third voltage used to effect the second voltage responsive to a high value on a base current sampling signal. A base-current-renewal circuit detects edge transitions on the data output signal and when the data output signal has no edge transitions for a period of time greater than a gap time defined in a PSI5 standard, sets the base current sampling signal high.

For a tank truck using an EBS, the present invention provides a tank truck rollover relieved control method based on electronic braking deceleration. Firstly, a tank truck rollover scene applicable to the relieved control method is defined; then, a least square method is adopted to establish a characterization function of tank truck braking deceleration; and finally, tank truck rollover relieved control is achieved on the basis of the characterization function of the braking deceleration and the EBS. The method fits out a function expression of the tank truck braking deceleration and can automatically select a proper braking deceleration under different rollover scenes according to kinematics information of the tank truck and vehicle body information; during tank truck braking deceleration, an operation of a driver is considered, so that man-machine effective combination is achieved; and relieved braking deceleration is conducted when the tank truck is in a potential rollover risk state, a situation that emergency braking is conducted when the tank truck has high rollover risk is avoided, and tank truck rollover control stability and effectiveness are improved.

Provided is a work vehicle capable of satisfying a user's demand to brake performance in a flexible manner. A wheel loader 1 comprises a controller 5 storing a plurality of control characteristics each of which is set such that a brake valve control pressure Pi of a solenoid proportional valve 45 increases as a pedal angle θ of a brake pedal 43 increases, and under the condition where a pedal angle θ is equal to or less than a predetermined pedal angle θ, an increase rate of the brake valve control pressure Pi with respect to the pedal angle θ varies. In a case where the pedal angle θ detected by a potentiometer 33 is equal to or less than the predetermined pedal angle θth, the controller 5, calculates the brake valve control pressure Pi based on the selected one control characteristic.

A controller in a first vehicle includes an electrical input port adapted to receive a first electrical signal, based on a presence of a first service brake demand associated with a first brake valve on the first vehicle, and a second electrical signal, based on a presence of a second service brake demand associated with a second brake valve on the first vehicle. The controller is capable of determining if at least one of the first electrical signal and the second electrical signal indicates the respective presence of the first service brake demand and the second service brake demand. An electrical output port is adapted to transmit an electrical deceleration signal based on the presence of the at least one of the first service brake demand and the second service brake demand. A speed reducing mechanism on a second vehicle is applied based on the electrical deceleration signal.

A foldable pedal apparatus of a vehicle may include a pedal pad, in which in a manual driving mode situation where a driver directly drives the vehicle, the pedal pad projects into an internal space of the vehicle and is popped up to be exposed toward the driver, whereas in an autonomous driving mode situation where the driver does not directly drive the vehicle, the pedal pad is inserted into a protection cover and is in a hide state where the exposure of the pedal pad toward the driver side is blocked, so that in the hide state of the pedal pad, a prominent internal design of the vehicle may be secured, and when the pedal pad is changed from the hide state to a popup state, the pedal pad is popped up through a small-sized panel hole formed on a footrest panel, and thus a high-tech image may be maximized.
