Throttle Control Malfunction

Journal of Failure Analysis and Prevention, 2008
We have all heard stories about runaway vehicles that accelerate uncontrollably and collide with other vehicles, crash into buildings or run people over. The circumstances often sound familiar and are sometimes tragic. The vehicle accelerates for no apparent reason and the driver is said to have been rendered helpless in an out-of-control machine.

Constrained optimal control of an electronic throttle

International Journal of Control, 2006
The overall vehicle performance is strongly influenced by the quality of the control of the electronic throttle -- a DC motor driven valve that regulates the inflow of air to the vehicle's engine. Designing a controller for the throttle system is a challenging task since one has to cope with two strong nonlinearities: the gearbox friction and the so ...

LPV Control of an Electronic Throttle

Volume 1: Aerial Vehicles; Aerospace Control; Alternative Energy; Automotive Control Systems; Battery Systems; Beams and Flexible Structures; Biologically-Inspired Control and its Applications; Bio-Medical and Bio-Mechanical Systems; Biomedical Robots and Rehab; Bipeds and Locomotion; Control Design Methods for Adv. Powertrain Systems and Components; Control of Adv. Combustion Engines, Building Energy Systems, Mechanical Systems; Control, Monitoring, and Energy Harvesting of Vibratory Systems, 2013
In this paper, a discrete-time electronic throttle model was developed based upon the parameters obtained through system identification. To design gain-scheduling controllers using LPV (linear parameter varying) scheme, the throttle was modeled as an LPV system, where the vehicle battery voltage and the non-linear friction coefficient are the ...

On the Toyota's Throttle Control Problem

2010 IEEE/ACM Int'l Conference on Green Computing and Communications & Int'l Conference on Cyber, Physical and Social Computing, 2010
This work tackles two research threads. The first thread evaluates the use of conventional design versus electronic engine control by applying real-time control theory. The second thread, which will be explored in a longer version of this paper, presents a formal method that determines if the system matches the specifications.

Throttle Control for Vehicle Following

Proceedings. The First IEEE Regional Conference on Aerospace Control Systems,, 2005
Throttle control design is an important part of Automated Vehicle Control System (AVCS). In this paper we design some throttle control schemes for vehicle following under constant time headway spacing policy. The schemes maintain a steady state inter-vehicle spacing decided by a desired time headway set by the driver.

Adaptive control of automotive electronic throttle

Control Engineering Practice, 2006
An electronic throttle is a DC servo drive which provides precise, drive-by-wire positioning of the throttle plate. This paper presents an electronic throttle control strategy consisting of a PID controller, and nonlinear friction and limp-home compensators.

Self-tuning control of an electronic throttle

Proceedings of 2003 IEEE Conference on Control Applications, 2003. CCA 2003., 2004
A Self-tuning strategy for an electronic throttle servo-system is proposed in order to account for the variations of DC motor armature resistance, battery voltage, and limp-home position. Different self-tuning algorithms have been derived depending on the availability of armature current sensor and control strategy auto-tuning procedure.

Adaptive pulse control of electronic throttle

Proceedings of the 2001 American Control Conference. (Cat. No.01CH37148), 2001
Precise control of electronic throttle is critical to driveability, fuel economy and emission performance of present day passenger vehicles. Due to cost, material and packaging constraints, the throttle open-loop dynamics may be fairly complex, exhibiting substantial nonlinearities among which friction plays a prominent role.
