The present disclosure is directed to systems and methods for detecting an overloaded vehicle and/or detecting when a load of a vehicle has shifted. In one form, the present disclosure provides a system comprising a memory and at least one processor in communication with the memory. The at least one processor is configured to: send a request to a controller of a vehicle requesting a vehicle mass; receive a response from the controller, the response comprising a calculated gross mass of the vehicle; determine a gross mass estimate of the vehicle; compare the gross mass estimate of the vehicle to an overweight value associated with the vehicle and determine whether the vehicle is overweight; and upon a determination that the vehicle is overweight, at least one of store information associated with the overweight determination in the memory or transmit a message with information associated with the overweight determination.

Systems and methods for detection of overloaded vehicle

A system for testing braking and steering systems of a vehicle includes a steering actuator to cause rotation of the steering wheel and electropneumatic modules associated with each wheel brake that include a solenoid controlling fluid communication between a brake actuator of the wheel brake and one of a fluid source and atmosphere. A controller transmits a first control signal to an electropneumatic module associated with a wheel brake on one side of the vehicle to actuate the solenoid of the electropneumatic module. The controller transmits a second control signal to the steering actuator to cause rotation of the steering wheel during actuation of the solenoid of the electropneumatic module and in a rotational direction towards the same side of the vehicle.

System and method for testing vehicle brake and steering systems

Systems and methods are provide for highway vehicle platoon maintenance management. Commercial highway vehicle platoon maintenance management is provided where it is desirable to determine traffic conditions around vehicles of the platoon, to share the determined traffic conditions with the other vehicles of the platoon, and to determine and share adaptive cruise control (ACC) parameters between the platooning vehicles for adjusting platoon inter-vehicle following distances based on the determined traffic conditions.

Using shared traffic information to support adaptive cruise control (ACC) between platooning vehicles

A brake controller in a vehicle determines braking profiles that may be exercised while operating the vehicle in autonomous or semi-autonomous conditions to decelerate the vehicle based on received commands or that may be exercised automatically in the event of a failure in a communication network of the vehicle or in other systems or components of the vehicle. The braking profiles decelerate the vehicle according to a deceleration profile. The execution of the deceleration profile may be initiated by a single command message received by the brake controller or it may be determined by the brake controller based on vehicle information. A safe state deceleration profile may be preselected by the controlling devices before the occurrence of a failure or an emergency situation, and then executed by the brake controller upon the occurrence of a failure or emergency.

Brake controller storing deceleration profiles and method using deceleration profiles stored in a brake controller

A method and controller are provided for delaying activation of autonomous emergency braking of a host vehicle, based on a determination that autonomous emergency braking is not needed because a forward vehicle in front of the host vehicle is turning out of the path of the host vehicle. The controller receives inputs from sensors arranged on the host vehicle and includes a processor for determining whether and when to activate autonomous emergency braking. The processor includes control logic that determines whether a forward vehicle is present in front of the host vehicle and whether the forward vehicle is expected to turn out of a path of the host vehicle prior to the host vehicle reaching a current position of the forward vehicle. Based on the inputs from the sensors, the control logic determines whether to delay activation of the autonomous emergency braking of the host vehicle for a time value.

Delay autonomous braking activation due to potential forward turning vehicle

A controller comprises an electronic communication line configured to receive a system brake request control signal representing a requested system brake application and an identified urgency. A hardware processor, configured to perform a predefined set of basic operations in response to receiving the system brake request control signal, is capable of: determining a maximum braking pressure to be applied during the system braking application based on the identified urgency; generating a first system brake mode control signal, based on the determined maximum braking pressure, to set an associated first valve to a first valve state; generating a second system brake mode control signal, based on the determined maximum braking pressure, to set an associated second valve to a second valve state, the maximum braking pressure during the system braking application being set by the first valve state and the second valve state; determining an activation profile for an associated modulator based on the determined maximum braking pressure; the controller transmitting, via the electronic communication line, the first system brake mode control signal, the second system brake mode control signal and modulator control signals according to the activation profile.

System and method for controlling an automated braking application

A braking controller and method in a towing vehicle towing one or more towed vehicles as a combination vehicle provides brake control of the one or more towed vehicles based on a level of braking force applied to the towing vehicle. A non-enhanced braking mode applies a first level of braking force to the towed vehicles in a predetermined reduced proportion relative to the level of braking force applied to the towing vehicle, and an enhanced braking mode applies a second level of braking force to the towed vehicles greater than the first level of braking force. A controller deceleration command input receives a deceleration command signal which is compared against predetermined threshold deceleration rate value or against a current deceleration value being executed by the combination vehicle and, based on a result of the comparisons, either the enhanced or the non-enhanced braking modes are implemented by the controller.
