A system for controlling a machine includes a machine configured to travel down a slope, the machine having a braking system, a sensor configured to generate a signal that indicates travel speed of the machine or a weight of the machine, and a controller. The controller is configured to receive the travel speed signal, estimate a rolling resistance of the machine, the rolling resistance being affected by a surface on which the machine travels, update the rolling resistance of the machine over time, and set an amount of braking based on the signal and the rolling resistance estimate.

An aspect of the present disclosure relates to a vehicle control system configured to control a vehicle. The vehicle control system includes an electronic control unit configured to limit a driving force to be applied to the vehicle based on a brake temperature that is a temperature of a friction brake provided on a wheel of the vehicle.

A system is operable for controlling a force applied on a trailer being towed by a vehicle is described to a desired force Fd. The trailer has brakes and an optional motor for providing a propelling force to the trailer. A force sensor senses fore-aft forces between the vehicle and trailer at all times while the trailer is being towed. A controller receives signals from the force sensor and is operatively connected to the trailer brakes and the motor. The system controls the force between a towing vehicle and a trailer to the desired force Fd, by any one of: (a) operating the brakes to apply a braking force to the trailer; (b) activating the motor to apply a propelling force to the trailer; and (c) operating the brakes and activating the motor to apply both a braking and a propelling force to the trailer.

A number of variations are disclosed including a computer program product and method of modifying brake-to-steer brake pressure commands, based on brake temperature, in real time as well as to create temperature dependent powertrain control and temperature dependent brake cooling.

According to one aspect of the present invention, there is provided a method for controlling an inertial driving mode of a commercial vehicle, the method comprising the steps of: determining at least one of a driving state of a commercial vehicle and a slope state of a road on which the commercial vehicle is driving; and setting a driving mode of the commercial vehicle to an inertial driving mode in response to the driving state of the commercial vehicle satisfying a first condition or the slope state satisfying a second condition, wherein the driving mode of the commercial vehicle is switched from the inertial driving mode to a power driving mode in response to a state of a braking means of the commercial vehicle satisfying a third condition.

Provided is a control apparatus for vehicle that improves operability for a driver. A control apparatus for vehicle switches the vehicle to a freewheeling mode in which power generated by an engine is not transmitted to drive shafts. The control apparatus for vehicle includes: a motor; a battery; friction brake equipment that generates frictional braking force on the vehicle; a temperature sensor that acquires temperature of the friction brake equipment; and a determiner that assesses the temperature of the friction brake equipment acquired by the temperature sensor. The friction brake equipment generates the friction braking force when the battery is fully charged. The freewheeling mode is deactivated in a case where the temperature of the friction brake equipment exceeds a predetermined temperature while the battery is fully charged and the vehicle is in the freewheeling mode.
