System and method for preventing overheating of axle in construction machine
The present specification relates to a system and a method for preventing overheating of an axle in a construction equipment. A system for preventing overheating of an axle in a construction equipment is mounted in the construction equipment and transmits driving power of an engine to a wheel, and the system includes: a brake pedal; a brake sensor which detects displacement of the brake pedal when the brake pedal is manipulated by an operator; an exhaust brake which is mounted in the engine and operates and controls an opening degree of an exhaust gas discharge passageway of the engine; and a control unit which adjusts the opening degree of the exhaust gas discharge passageway by controlling the exhaust brake corresponding to the displacement of the brake pedal when manipulation of the brake pedal is detected by the brake sensor.
Electric brake device
This electric brake device includes: a brake rotor, a friction member, a friction member operator, an electric motor, and a controller which controls, by controlling the electric motor, a braking force generated as a result of contact between the friction member and the brake rotor. The electric brake device includes a vehicle speed estimator which estimates the speed of the vehicle having the electric brake device mounted thereon. The controller includes a power limiter which limits the power that drives the electric motor. When an estimated vehicle speed, which is the speed of the vehicle estimated by the vehicle speed estimator, is in a determined low-speed range, the power limiter limits the power in accordance with a condition that has been determined such that the maximum power consumption of the electric brake device decreases in accordance with decrease in the estimated vehicle speed.
Operating method for an automatic transmission of a motor vehicle
The invention relates to an operating method for an automatic transmission, particularly for an automatic variable-speed transmission and/or dual-clutch transmission, for a motor vehicle. The automatic transmission can be operated in a cost-effective manner, particularly with reduced component wear and increased service life, and/or the driving comfort of the vehicle can be improved such that when lifting of at least one driven vehicle wheel off the roadway during braking is detected by the operating method, then for the length of said braking process, in the event of an incomplete gear change into a gear of the transmission, the engagement of a gear is prevented and/or the beginning of a gear change into a gear of the transmission is prevented.
Auto gain adjusting trailer brake controller
In various example embodiments, a system and method for determining a trailer brake gain signal for trailer brakes on a trailer being towed by a vehicle, and applying brakes to the trailer is disclosed. A method includes: providing predetermined calibration settings relating motor drive force to motor speed for a vehicle travelling at various speeds and providing accelerometer data. The method then determines that one or more vehicle performance parameters fall within threshold ranges and then determines both the vehicle weight and the trailer weight. The brake gain signal is determined based on the ratio of the current trailer weight and the original trailer weight. The brake gain signal is then transmitted to a trailer brake controller that applies trailer brakes according to the brake gain signal.
