Patent number: 11512454Abstract: A system for controlling an engagement operation between first and second movable machines includes a separation sensor, a relative speed sensor and a controller. The separation sensor determines a separation distance between the first and second machines. The relative speed sensor determines a relative difference in speed between the first and second machines. The controller determines the separation distance between the first and second machines, decelerates the first movable machine when the separation distance is within a deceleration zone, determines a relative difference in speed between the first and second machines, and generates an engagement speed command to operate the first movable machine at a first ground speed equal to a second ground speed of the second movable machine plus a relative engagement speed when the separation distance is within a buffer zone.Type: GrantFiled: July 5, 2018Date of Patent: November 29, 2022Assignee: Caterpillar Inc.Inventors: David C.

Patent number: 9951795Abstract: Engine anti-idling and restart may be implemented in a machine having a power source, a movable work tool, a pump driven by the power source, an actuator receiving fluid from the pump and moving the work tool, a high-pressure fluid reservoir, and an assist motor operatively connected to the power source. Engine restart may include detecting operator input to start the power source, and fluidly connecting the fluid reservoir to the assist motor to assist in starting the power source in response to detecting the operator input. Prior to shutting down the power source during anti-idling, fluid from the pump may be input to the assist motor, pressurized and communicated to the high-pressure fluid reservoir in response to determining that idle condition exists and a reservoir charge pressure is less than a reservoir minimum restart pressure needed to restart the power source.Type: GrantFiled: March 25, 2015Date of Patent: April 24, 2018Assignee: Caterpillar Inc.Inventors: Tonglin Shang, Pengfei Ma, Dayao Chen, Jeremy Peterson, Emily Anne Morris

Patent number: 8839617Abstract: A novel energy saving mode of charging an accumulator in an electro-hydraulic system is disclosed involving toggling the position of a fan isolation valve from the flow-passing position, where the flow is driving a fan motor thereby maintaining a fan in an on position, to the flow-blocking position where the flow is inhibited from driving the fan motor thereby causing the fan to turn off, when the time to charge an accumulator is less than the period of time that the fan may be off and still allow for the cooling requirements of the engine to be satisfied. By diverting fluid flow from driving the fan motor to charging the accumulator, the disclosed energy saving mode allows for a greater flow of fluid to be delivered to the accumulator for charging, making it possible to charge the accumulators quicker and more efficiently while maintaining the cooling requirements of the engine. The energy saving mode of operation may illustratively be used in a hystat fan and hybrid system.Type: GrantFiled: September 30, 2011Date of Patent: September 23, 2014Assignee: Caterpillar Inc.Inventors: Bryan Nelson, Jeremy Peterson
