The one or more processors determine whether or not the detection values by the sensors differ by a predetermined threshold value or more. The one or more processors determine a reference value based on the detection values by the sensors, by a determination method set in accordance with a control using data regarding the detection target, when the detection values by the sensors differ by the predetermined threshold value or more. The one or more processors carry out the control based on the reference value.

A method for determining a continuous braking power for a vehicle, in particular a commercial vehicle, the method having the steps: determining an ambient temperature; determining a speed, wherein the speed is representative of the speed of the vehicle, in particular the commercial vehicle; determining a thermal emission per unit time of a friction braking device on the basis of the ambient temperature and the speed; and determining the continuous braking power of the friction braking device on the basis of the thermal emission per unit time.

An embodiment vehicle includes a transmission configured to set a travel direction of the vehicle, an indoor camera configured to capture a driver of the vehicle, a cluster configured to display information while the vehicle is in operation, and a main controller configured to, in response to the transmission being shifted to reverse, identify whether a gaze of the driver captured by the indoor camera is directed to a rear of the vehicle and, in response to a determination that the gaze of the driver is not directed to the rear, control to display a warning message.

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.

An emergency brake system for a heavy-duty vehicle, comprising: a pressure sensor arrangement configured to issue a first signal, S1, upon determination that the pressure in a regular brake circuit is zero or below a predefined pressure threshold value, a speed sensor configured to issue a second signal, S2, upon determination that the speed of the heavy-duty vehicle exceeds a predefined speed threshold, a parking-brake sensor configured to issue a third signal, S3, upon determination that the parking brake is in an applied state, a retarder brake configured to decelerate the heavy-duty vehicle upon activation of the retarder brake, a processing circuitry configured to activate the retarder brake upon receiving all of said three signals S1, S2 and S3.

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.
