A vehicle stop determination device includes: a vehicle wheel speed sensor that outputs a signal according to a rotational speed of vehicle wheels; an acquisition unit that acquires a wheel speed at a predetermined reference time that a vehicle decelerates, based on an output signal of the vehicle wheel speed sensor; a derivation unit that derives a stopping position where the vehicle stops, based on the wheel speed acquired by the acquisition unit; and a determination unit that executes a stop determination to determine that the vehicle has stopped, when a difference distance between a position of the vehicle after the reference time and the stopping position is a stop determination value or less.

A method is for identifying fault-induced temperature changes at wheel ends of a vehicle. At least two of the wheel ends have a wheel speed sensor having a temperature sensor configured to measure around its position a sensor temperature in a sensing region. The method includes: retrieving a first sensor temperature measured by a first temperature sensor at a first wheel end; and retrieving a second sensor temperature measured by a second temperature sensor at a second wheel end; determining a temperature deviation on the basis of the first sensor temperature and the second sensor temperature; comparing the temperature deviation with a deviation limit value; and outputting a notification when the deviation limit value is exceeded, which notification includes that a temperature change induced by a fault has been detected at least at one of the wheel ends that have a wheel speed sensor having a temperature sensor.

A vehicle trajectory for transitioning out of a deceleration trajectory may be determined based on predicted vehicle state(s) and/or environmental condition(s). A determination about whether to transition into the determined trajectory may be based on whether the condition that triggered the deceleration trajectory still exists, whether the determined trajectory meets safety criteria, and/or whether an alternative deceleration trajectory is warranted. The determination may be used to determine which trajectory to control the vehicle and/or to inform the vehicle's driving behavior.

A vehicle brake disc temperature monitoring unit includes (i) a temperature collection module, which collects temperature values near the brake disc that change over time during vehicle braking, (ii) a temperature estimation module, which uses an observation model and a state estimation model to estimate the temperature of the brake disc based on the temperature values collected by the temperature collection module and the estimated values of the actual temperature of the brake disc through the Kalman filtering process, and (iii) a control module, which adjusts and controls the braking state of the vehicle braking system through the estimated temperature values and the detection values of the temperature sensor. In view of the above, it is possible to use a temperature sensor that is not in contact with the brake disc and utilize the Kalman filtering method to effectively estimate the temperature of the brake disc when it is impossible to directly measure the temperature of the brake disc using the temperature sensor installed on or abutting the brake disc, improving monitoring accuracy and allowing the safe and reliable monitoring of the vehicle's braking system and thereby improving the safety of the vehicle during driving.

A method for determining a braking distance of a vehicle, wherein a coefficient of friction (COF)actual between a brake lining and a brake disc is calculated as a function of a tensioning force Fd, a vehicle velocity V and a temperature of the frictional layer Tdisc, wherein the temperature of the frictional layer Tdisc is updated dynamically on the basis of the coefficient of friction COFactual in order to calculate a braking distance which approaches reality.

A method for operating brakes of a vehicle includes: transmitting vehicle location information acquired from a location detection device mounted on the vehicle to a remote server, receiving first remote data on whether the vehicle is located within a goods delivery zone that is calculated based on the location information from the remote server, switching a vehicle operation mode to a brake automatic operation mode if a value of the first remote data is determined to indicate that the vehicle is located within the goods delivery zone; determining whether a predetermined first condition is satisfied in the automatic operation mode; and transmitting an instruction to a vehicle integration controller mounted on the vehicle to operate the brakes of the vehicle in a first manner if the first condition is determined to be satisfied. A device for operating brakes of the vehicle may perform the method.

Example embodiments relate to triple redundant brake systems for trucks and other types of vehicles. Disclosed systems offer additional redundancy for braking applications by incorporating a third service brake actuator (e.g., a third ECU), which may be installed parallel to the second controller (e.g., a second ECU). In some examples, the third service brake actuator is an electronically activatable pressure valve and can be implemented using pneumatic select-high valves. These valves can be used to perform a mechanical max arbitration between pressure provided by the second controller and the third controller.
