摘要： An overrunable test vehicle including an electronically-controlled anti-slip braking system for reducing wheel slip during rapid deceleration comprising: a chassis, at least one electric motor connected to a first axle, a hydraulic braking system connected with the chassis and at least a second axle, a rotational speed sensor for determining a rotational speed of a connected axle, a ground speed sensor, and a controller connected with the electric motor, the hydraulic braking system, the rotational speed sensor, and the ground speed sensor. The controller is configured to calculate a difference between the rotational speed of the axle and the ground speed of the chassis to determine a slip threshold of the wheels, actuate the hydraulic brake system to apply a first stopping force, control at least one motor parameter of the electric motor to apply a second stopping force. The first and second stopping forces combined are less than the slip threshold of the wheels such that the chassis rapidly decelerates free of a wheel slip condition.

摘要： A sensor monitoring device that comprises: a first controller ECA into which a detected value Smn from a sensor SMN is inputted via a first signal line LMA; a second controller ECB into which the detected value Smn is inputted via a second signal line LMB; and a communication bus CMB that transmits signals between the first controller ECA and the second controller ECB. The second controller ECB reads in the detected value Smn as a second processing value Smb and transmits the second processing value Smb to the first controller ECA via the communication bus CMB. The first controller ECA reads in the detected value Smn as a first processing value Sma, receives the second processing value Smb, and, on the basis of the first processing value Sma and the second processing value Smb, determines the suitability of the first processing value Sma.

摘要： An emergency braking monitoring system includes a wheel assembly having a first wheel, an emergency braking monitoring unit coupled to the wheel assembly, and a locked wheel annunciation center coupled to the emergency braking monitoring unit for annunciation purposes. The emergency braking monitoring unit generates a fault annunciation signal based on a determination as to whether a first wheel speed value originating from the first wheel of the wheel assembly is a predetermined amount less than a reference value for a persistence time.

摘要： When detecting a maladjusted brake component on a commercial vehicle, wheel end temperature is determined as a function of resistance measured by a wheel speed sensor at a wheel end. The measured temperature is compared to low and high temperature thresholds defined by a thermal model, as well as to one or more other wheel speed sensor temperatures. If the measured temperature is below the low temperature threshold and substantially different than the one or more other wheel speed sensors, the brake is determined to be under-adjusted and brake force at the under-adjusted brake is increased. If the measured temperature is above the high temperature threshold and substantially different than the one or more other wheel speed sensors, then the brake is determined to be over-adjusted, and brake force is reduced or modulated at the over-adjusted brake to prevent overheating.

摘要： A vehicle brake hydraulic pressure control apparatus includes a pressure increasing section, a holding section, and a determination section and wheel speed sensors. The pressure increasing section increases a brake hydraulic pressure by driving a motor. The holding section holds a brake hydraulic pressure. The determination section determines as to whether or not the motor is malfunctional. The wheel speed sensors detect as to whether or not a vehicle which is at a halt starts to move. If the wheel speed sensors detect that the vehicle starts to move while the holding section is executing a holding control, the pressure increasing section executes a hydraulic pressure re-increasing control by driving the motor, and the determination section determines as to whether or not the motor is malfunctional based on a detection result by the wheel speed sensors after the brake hydraulic pressure is started to be increased by the hydraulic pressure re-increasing control.

摘要： A method for circuit separation testing in a double gearwheel pump having two gearwheel pumps includes charging one of the two gearwheel pumps with pressure and measuring the pressure build-up in the charged gearwheel pump and/or the pressure-build up in the other gearwheel pump. The pressure build-up is preferably realized by the gearwheel pump itself. The gearwheel pumps have a common pump shaft and are preferably configured as hydraulic pumps of a hydraulic vehicle brake system with slip control. The method detects any leak at the leadthrough of the pump shaft through a partition wall between the two gearwheel pumps.

摘要： The running control device and method according to the present invention are those for determining abnormality of a longitudinal acceleration sensor which detects vehicular longitudinal acceleration that is used in a vehicle running control. An integrated value of a vehicular longitudinal acceleration that is detected by the longitudinal acceleration sensor is calculated, and determination whether or not the longitudinal acceleration sensor is abnormal is conducted on the basis of the integrated value and a vehicle speed based on vehicle wheel speeds. The calculation of the integrated value is initiated when a situation where the vehicle speed based on vehicle wheel speeds is zero and the increasing rate of the detected vehicular longitudinal acceleration is equal to or larger than a reference value for the increasing rate continues for a period which is equal to or larger than a reference value for the initiation of calculation.
