The cruise control system automatically controls the vehicle speed. It allows the The cruise control system is controlled by the engine control module (ECM). The cruise control system interacts with the driver, the speed control device ( throttle) and the external environment despite various interfaces in order to keep the. PDF | 25+ minutes read | In this article we would like to present cruise control realization. This cruise control is presented as mechanical device.

Cruise control state: In cruise control state, set point speed of the host Figure 6 Oskar Electrical Vehicle vehicle is feed to low level controller as reference speed of vehicle. Host vehicle tracks the set point speed in cruise 3. It is kept in the cruise control state when there is no ARS Long range radar sensor is used as sensing vehicle front of the host vehicle and set point speed is close unit. If there is a and with an accuracy of 0. It has open can protocol, target vehicle and target vehicle speed is bigger than set and baud rate is kbps.

The radar sensor is able to detect 64 still kept in cruise control state. ACC also needs an encoder to measure the host vehicle speed. Industrial encoder is used to 3. The PID controller is designed for an electrical the sensing unit is realized using robot operating system vehicle Oskar figure 6 using Cohen-Coon method. The low level controller is realized using a free RTOS based embedded controller.

The details of simulation and test for each subsystem are given below. The reference speed value is given through HMI unit and the controller calculates motor driver inputs using the feedback from encoder. Other vehicles: Target vehicle 0 0 10 20 30 40 50 Object Lateral distance m Figure 9. Various test scenarios are applied. In this figure the relative distance, host vehicle speed, and the host vehicle acceleration are given in the first, second and third row respectively.

The driver sets Figure 9. The time headway was selected as small. When the ACC is on there was a relative distance of m. Then state machine switches to distance control state at 32nd sec and the control algorithm track the safety distance of 37 m see Figure 8. Off ACC: Each subsystem was designed and tested independently Figure 8 The high level controller test result considering the data interface.

High level unit makes the conscious level decisions. Gazebo simulator The raw data obtained from the radar sensor is will be used for integration tests of all system. Real time processed to determine the moving objects. It can detect 6 application of ACC system will be on Oskar electrical different types of objects up to m. The long range radar vehicle see Figure 6. The one in the circle corresponds to the target provided a flexibility in development.

Note that other vehicle. ADAS feature can also be easily implemented in this architecture.

The cruise control systems of some vehicles incorporate a "speed limiter" function, which will not allow the vehicle to accelerate beyond a pre-set maximum; this can usually be overridden by fully depressing the accelerator pedal.

Cruise control

Most systems will prevent the vehicle accelerating beyond the chosen speed, but will not apply the brakes in the event of overspeeding downhill. On vehicles with a manual transmission , cruise control is less flexible because the act of depressing the clutch pedal and shifting gears usually disengages the cruise control. The "resume" feature has to be used each time after selecting the new gear and releasing the clutch. However, when used incorrectly cruise control can lead to accidents due to several factors, such as:.

Some modern vehicles have systems for adaptive cruise control ACC , which is a general term meaning improved cruise control. These improvements can be automatic braking or dynamic set-speed type controls.

Automatic Braking Type: Some systems also feature forward collision warning systems, which warn the driver if a vehicle in front—given the speed of both vehicles—gets too close within the preset headway or braking distance. Dynamic Set Speed Type: The dynamic set speed uses the GPS position of speed limit signs, from a database.

Some are modifiable by the driver. Non-Braking Type: The speed can be adjusted to allow traffic calming. Dynamic radar cruise control: Vehicles with adaptive cruise control are considered a Level 1 autonomous car , as defined by SAE International.
