An electronic control unit (ECU) is disclosed. The ECU may detect an emergency stopping event associated with a vehicle. The ECU may determine, based on detecting the emergency stopping event, that electro-hydraulic brakes of the vehicle are in a disabled mode. The ECU may determine, based on determining that the electro-hydraulic brakes are in the disabled mode, a position of a brake pedal of the vehicle. The ECU may override, based on the position of the brake pedal, the disabled mode to engage the electro-hydraulic brakes during the emergency stopping event.

Automatic break application for emergency stop

A construction machine includes a system and method for performing a lockout or stand down of the machine to prohibit movement of the machine or one or more components of the machine, without shutting down the machine. Information about the status of the machine or a component thereof can be collected and relayed to an electronic control module (ECM) to determine whether to lockout the construction machine. If appropriate, the ECM can command lockout to an electrical component of the machine or component to prohibit movement of the machine or component until the lockout is released.

Locking out a machine to prohibit movement

An electronic control unit (ECU) is disclosed. The ECU may receive a command associated with a vehicle. The ECU may actuate one or more lights on the vehicle in a first mode based on receiving the command. The ECU may transmit, while actuating the one or more lights in the first mode, the command to a vehicle controller associated with the vehicle. The ECU may actuate the one or more lights in a second mode based on receiving an acknowledgement of the command from the vehicle controller.

Collision avoidance activation lights

The temperature of a machine component is controlled by transferring heat generated by a torque converter under restricted conditions to the component. The machine includes a circulating fluid system configured to transfer heat from the torque converter to the remotely positioned machine component. A controller is configured to sense the temperature of the component, and to restrict motion of the torque converter turbine when the sensed temperature is below a desired temperature. Heat generated by the torque converter under the restricted condition is transferred through the circulating fluid system to the remote component, such as the machine power source, to control the temperature thereof.
