Patent number: 11639694Abstract: A vehicle control system includes an accelerator sensor which detects an accelerator opening, a target acceleration setting unit which sets a target acceleration of a vehicle based on the detected accelerator opening, a target torque setting unit which sets a target torque of a drive source based on the set target acceleration, and a drive source controller which controls the drive source to generate the set target torque. In a case where the target acceleration at a time when the accelerator opening is increased is set as a depression-increasing target acceleration and the target acceleration at a time when the accelerator opening is decreased is set as a pedal-returning target acceleration, under the same condition of the accelerator opening, the target acceleration setting unit sets the target acceleration such that the pedal-returning target acceleration becomes lower than the depression-increasing target acceleration.Type: GrantFiled: February 10, 2022Date of Patent: May 2, 2023Assignee: Mazda Motor CorporationInventors: Takefumi Takada, Yuki Ishiyama

Patent number: 11635035Abstract: Engine controllers and control schemes are provided for managing engine state transitions requiring increased compressor pressure ratios in turbocharged engines. In some circumstances, turbo lag can be mitigated by initially transitioning the engine to an intermediate engine state that directly or indirectly increases airflow through the engine and turbocharger relative to what would be possible if the engine were immediately commanded to operate at the target engine state. After reaching a point where the desired torque is actually generated at the intermediate engine state, the operational settings are gradually reduced to the target effective firing density while increasing the operational compressor pressure ratio to the target compressor ratio.Type: GrantFiled: January 5, 2022Date of Patent: April 25, 2023Assignee: Tula Technology, Inc.Inventors: Elliott A.
