ELECTRONIC THROTTLE CONTROLS / DRIVE-BY-WIRE
The first U.S. applications of ETC (Electronic Throttle Controls) were introduced by DriveSol in the 1993 model year on accelerator pedal assemblies for light duty diesel trucks and diesel vans.
 Today, ETC pedal systems are the preferred technology because of their inherent ability to enhance overall engine management while reducing the production costs associated with the assembly of the accelerator pedal system in the vehicle. DriveSol manufacturers over 4.5 million ETC pedals per year in North America, Europe and China offering both contact and non-contact ETC technology.
ETC BENEFITS
- Electronic control reduces vehicle emissions
- Electronic control enhances fuel economy
- Complex mechanical linkages that are costly to engineer and install are eliminated
- The ETC design concept improves vehicle packaging and serviceability
- Integration of cruise control eliminates additional mechanical linkages
- Electronic traction control can also be linked
NEW DRIVESOL ADVANCEMENTS INCLUDE
- Better pedal effort hysteresis
- Pulse Width Modulated sensors
- Non-contact sensors
- More compact, lightweight pedals
- New mounting configurations
MODULAR CONTACT SENSOR ETC DESIGNS
|
Accelerator pedals that use a modular contact sensor design are the most common accelerator pedals in use in the automotive industry. This proven technology uses a modular sensor mechanism that actually measures the change in electrical output to provide the infinitely variable acceleration/deceleration signal based on the position of the pedal.
A critical design requirement is the pedal “feel” that is produced by the pedal design that mechanically creates the consistent pedal effort hysteresis.
Accelerator pedals with contact sensors feature:
- Resistive Potentiometers
- Fully Redundant
- Support For All Output Formats
- Use Thick Film Technology
- Direct Drive, No Linkages
- Solderless Terminals
- Laser Trimming at Final Assembly
- Weigh less than 300 grams

MODULAR NON-CONTACT SENSOR ETC DESIGNS
|
Advanced ETC pedal designs are using non-contact sensor designs to provide the necessary electrical measurement of the pedal position. This type of sensor provides optional signal outputs that include digital, analog as well as pulse-width-modulation. In application these types of sensors can provide outputs that can be better controlled, and in some cases can improve packaging situations where smaller sensors could be beneficial.
Accelerator pedals with non-contact sensors feature:
- Hall Effect Technology(magnetic field)
- Fully Redundant
- Support For All Output Formats
- Proven Technology
- Direct Drive, No Linkages
- Solderless Terminals
- Programmability Through Connector
- Reprogrammability
- Weigh less than 300 grams
