Rostra leads the way in designing and developing add-on cruise control systems, specifically for vehicles with Electronic Throttle Control (ETC), often called “drive-by-wire.” Our decades of research and development in vehicle testing and software architecture, focusing on passenger vehicles, have made us the top aftermarket cruise control provider. This expertise allows us to offer seamless integration with your vehicle’s OBDII port for optimal performance.
Our add-on cruise control units utilize an Obdii Port Cruise Control Kit to manage vehicle speed. This kit includes a custom E-Cruise Module, precisely fitted accelerator pedal T-harnesses for various vehicles, Onboard Diagnostic (OBD) port interface harnesses, and control switches designed to blend seamlessly into your steering column and dashboard. Leveraging the vehicle’s OBDII port, the system monitors speed and adjusts the throttle accordingly.
The E-Cruise Module acts as the system’s “brain.” With the accelerator pedal interface harness, it intercepts communication between the pedal position sensor and the vehicle’s Electronic Control Unit (ECU). Through the OBDII port cruise control kit connection, the module constantly monitors vehicle speed and load, instructing the ECU to adjust the electronic throttle to maintain the desired speed. When cruise control is disengaged (via the Off/Cancel button, brake pedal, or clutch pedal), the module relinquishes control, returning full functionality to the accelerator pedal.
Understanding the Electronic Cruise Control System Layout
A typical electronic cruise control system, utilizing an OBDII port cruise control kit, includes:
- The E-Cruise Module
- Accelerator pedal harness connection
- OBDII port connector
- Control switch
- Universal clutch disengagement switch (for some manual transmission vehicles)
Rostra’s Meticulous Product Development Process
Rostra develops platform-specific applications and offers vehicle-specific installation kits for optimal performance with your OBDII port cruise control kit. This precision is crucial because cruise control software must send unique commands to each vehicle’s onboard computer via the CAN bus system. “Universal” systems can’t safely create or transmit these specific signals. Our development process involves:
- Recording data from the vehicle’s CAN bus to identify the signals needed to control speed.
- Selecting the appropriate E-Cruise Module based on the required signals.
- Writing the vehicle-specific software to the E-Cruise Module within a Faraday cage to minimize outside interference.
- Rigorously testing the loaded software to ensure accurate speed holding between 31 and 80 MPH.
- Final validation and permanent installation of the control switch after meeting strict operational parameters.
Frequently Asked Questions About OBDII Port Cruise Control Kits
Q: How long does development take?
A: Development time depends on vehicle availability for testing. Typically, it takes about four weeks after initial testing, instruction creation, software verification, and validation on multiple trim levels.
Q: Why choose a Rostra system?
A: Rostra prioritizes quality control. Our ISO 9001 certified and TS 16949 compliant manufacturing plant undergoes rigorous audits and continuous improvement. We confidently offer a 3-year/36,000-mile guarantee.
Q: Is DIY installation recommended?
A: Due to the complexity of vehicle electronics, professional installation is recommended. While some kits are plug-and-play, they require proper grounding and a 12-volt ignition source, with soldered connections for safety and to avoid damage to the onboard computer.
Q: Why avoid “universal” systems?
A: “Universal” systems often lack quality control and proper validation. They may not communicate correctly with your vehicle’s computer, potentially reducing fuel efficiency or interfering with emergency systems. A Rostra OBDII port cruise control kit ensures compatibility and safety.
