Device for detecting wheel speed
A wheel speed detection device according to one aspect of the present disclosure is installable on a wheel bearing which comprises an outer ring and an inner ring coupled to a rotating shaft and relatively rotated relative to the outer ring about the rotating shaft. The wheel speed detection device comprises a first target concentrically coupled to the rotating shaft, a second target disposed along an outer circumference of the inner ring, a cap coupled to the outer ring to cover the first target and the second target, a first sensor disposed in the cap and configured to detect a variation in magnetic field of the first target due to a rotation of the rotating shaft, and a second sensor disposed in the cap and configured to detect a variation in magnetic pole of the second target due to a rotation of the inner ring.
Arrangement of a parking lock in a vehicular transmission
A parking lock in a vehicle transmission includes a locking mechanism for locking and releasing a parking interlock gear (1) and an actuating unit. The actuating unit is coupled via a coupling mechanism to the locking mechanism in order to actuate the locking mechanism between an interlock position and a release position of the parking interlock gear (1). The parking lock is arranged on an intermediate plate (2) in a housing of the vehicle transmission.
AIRCRAFT SYSTEM
An aircraft system for an aircraft having a controller configured to determine, based on a criterion indicative of an aircraft condition or a runway condition, a maximum braking level able to be applied to a brake of the aircraft in an emergency braking mode.
Shutoff valve control system
Systems and methods for shutoff valve control are provided. The system may receive a first hardware logic input, a second hardware logic input, and a weight-on-wheels (WOW) status wherein each of the first hardware logic input, the second hardware logic input, and the WOW status report a binary true or a false. The system may open the shutoff valve when each of the first hardware logic input, the second hardware logic input, and the WOW status report true. The system may close the shutoff valve when any of the first hardware logic input, the second hardware logic input, and the WOW status report false.
System for predicting road surface friction coefficient
A system for predicting a road surface friction coefficient includes an external information acquisition part, a tire information acquisition part, and a friction coefficient prediction part. The external information acquisition part configured to acquire external information on a disturbance factor that affects a condition of a road surface on which a target vehicle travels. The tire information acquisition part configured to acquire tire information indicating a condition of a tire of the target vehicle. The friction coefficient prediction part configured to predict a friction coefficient between the tire and the road surface based on the tire information acquired by the tire information acquisition part and the external information acquired by the external information acquisition part. The friction coefficient prediction part predicts a friction coefficient of a road surface ahead of the target vehicle in a traveling direction.
AUTOMATIC BRAKE DEVICE FOR INDUSTRIAL VEHICLE AND INDUSTRIAL VEHICLE HAVING THE SAME
An automatic brake device for an industrial vehicle includes a brake pedal, a brake master cylinder, and an actuator that is operated during automatically braking, and configured to generate brake pressure in the brake master cylinder. The automatic brake device includes a first pivotable link member and a second pivotable link member. The brake pedal includes a pedal-side contact portion. The second pivotable link member includes a second link-side contact portion. The first pivotable link member includes a first contacted portion and a second contacted portion. The first pivotable link member is pivoted by the pedal-side contact portion pressing the first contacted portion while the brake pedal is stepped on, and pivoted by the second contacted portion pressing the second contacted portion while the actuator is operated.
Work machine speed control braking
A machine includes an engine, a brake system, a speed sensor, a grade sensor, a load sensor, and a controller. The controller is configured to: determine a grade force based on the weight of the machine and the grade at which the machine is disposed; determine a deceleration force based on a target deceleration and the weight of the machine; monitor the speed at which the machine is traveling; determine an actual deceleration of the machine based on the monitored speed at which the machine is traveling; determine a deceleration error based on a difference between the actual deceleration and the target deceleration; determine a force correction based on the deceleration error; and control the brake system to apply a total brake force equal to the sum of the grade force, the deceleration force, and the force correction.

POWERTRAIN TO FRICTION BRAKE STANDSTILL HANDOFF FOR ONE PEDAL DRIVE
A method for controlling a vehicle includes monitoring the vehicle speed for a first threshold in conjunction with a driver request for negative torque, after which the method comprises increasing a friction braking ratio. The method further comprises monitoring the speed of the vehicle for a second threshold, wherein the second threshold is lower than the first, after which the method comprises solely using the friction braking for braking holding torque.
BRAKE ASSIST DURING VEHICLE ONE PEDAL DRIVE
A vehicle includes friction brakes, an electronic park brake system, and controllers. The controllers, responsive to the vehicle coming to a stop, and the vehicle being on plug, a driver door of the vehicle being open, or a driver seatbelt being unbuckled, issue a standstill friction brake request for the friction brakes and an electronic park brake request for the electronic park brake system. The controllers also, responsive to engagement of the electronic park brake system, discontinue the issue of the standstill friction brake request.
