Filed:

Sep 18, 2019

Appl. No.:

16/574972

Inventors:

- Plano TX, US
Alejandro M. Sanchez - Ann Arbor MI, US
Motonori Kimura - Ann Arbor MI, US

International Classification:

B60W 40/076
B60W 30/18

Abstract:

A system for dynamically maintaining a vehicle speed during a change in road grade comprises a first sensor configured to detect a depression amount of an accelerator pedal and a second sensor configured to monitor the vehicle speed. The system further comprises a vehicle speed control module configured to: receive an indication that the accelerator pedal is depressed; receive an indication of the vehicle speed; determine that the pedal has been depressed within a threshold amount for a threshold time period; determine that the vehicle speed has been maintained within a threshold for the threshold time period; determine whether the change in the road grade is less than a threshold grade; and, based on a determination that the change in the road grade is less than the threshold, automatically adjust a load on a power source of the vehicle to maintain the vehicle speed during the change in road grade.

International Classification:

B60W 40/06
B60W 30/19
B60W 10/02
F16H 61/04

Abstract:

Disclosed is a vehicle road load compensation system that includes an accelerator pedal, a throttle, a transmission wherein a vehicle torque is generated proportional to the transmission gear and the motor power, and a control unit disposed within the vehicle and configured to receive real-time sensor data relating to the road load of the vehicle. The control unit includes a real-time throttle map relating the accelerator pedal position to the throttle position, such that a given accelerator pedal position directs a corresponding target throttle position. The control unit also includes a real-time shift map relating a desired transmission gear to a current transmission gear, vehicle speed, and throttle position. In response to the sensor data, the control unit updates the throttle map and shift map such that the vehicle torque is altered based on the road load of the vehicle. The controller may also update a real-time torque converter lockup map.

B60W 30/02
F16H 61/04

Abstract:

Disclosed is a vehicle acceleration compensation system, including an accelerator pedal, throttle, and a transmission configured to shift between two or more fixed gears, wherein each gear relates the motor power to a vehicle torque. The system also includes a control unit configured to receive data from one or more sensors. The control unit includes a real-time throttle map relating the accelerator pedal position to the throttle position, such that a given accelerator pedal position directs a corresponding target throttle position, and a real-time shift map relating a desired transmission gear to a current transmission gear, current vehicle speed, and current throttle position, such that a given vehicle speed, given throttle position, and given transmission gear directs a corresponding target transmission gear. In response to sensor data, the control unit updates the throttle map and shift map such that the vehicle torque is altered to produce a desired acceleration value.
