Area Of Science
- Human-computer interaction
- Automotive engineering
- Transportation psychology
Background
- Personalized driving styles in high-level automation (SAE levels 4-5) enhance user experience.
- The transferability of these benefits to intermediate automation levels (SAE levels 2-3) remains underexplored.
Purpose Of The Study
- To investigate the impact of personalized driving speed on user experience and takeover performance in intermediate driving automation (SAE levels 2-3).
- To assess the mediating role of perceived safety and moderating role of trust in the relationship between personalized speed and comfort.
Main Methods
- A simulator study involving 52 participants.
- Phase 1: Recording of individual driving speeds.
- Phase 2: Participants experienced automated driving at either their personalized speed or 20 km/h faster, with occasional takeover requests.
Main Results
- Personalized driving speed significantly increased comfort, mediated by perceived safety.
- Trust in automated systems moderated the effect of driving speed on perceived safety.
- Personalized speed reduced brake force and longitudinal acceleration during takeovers, improving smoothness.
Conclusions
- Personalized automated driving speeds offer benefits in comfort and safety for intermediate automation (SAE levels 2-3).
- This personalization strategy can enhance traffic flow and overall safety.
- Findings support the extension of personalized driving style benefits beyond high-level automation.

Controller configurations are crucial in a car's cruise control system because they manage speed over time to maintain a consistent pace regardless of road conditions, thereby meeting design goals. In traditional control systems, fixed-configuration design involves predetermined controller placement. System performance modifications are known as compensation.
Control-system compensation involves various configurations, most commonly series or cascade compensation, in which the controller...
In automotive engineering, car suspension systems often employ Proportional Derivative (PD) controllers to enhance performance. PD controllers are utilized to adjust the damping force in response to road conditions. A controller, acting as an amplifier with a constant gain, demonstrates proportional control, with output directly mirroring input.
Designing a continuous-data controller requires selecting and linking components like adders and integrators, which are fundamental in Proportional,...
The importance of understanding acceleration spans our day-to-day experiences, as well as the vast reaches of outer space and the tiny world of subatomic physics. In everyday conversation, to accelerate means to speed up. For instance, we are familiar with the acceleration of our car; the harder we apply our foot to the gas pedal, the faster we accelerate. The greater the acceleration, the greater the change in velocity over a given time. Acceleration is widely seen in experimental physics. In...
Cruise control systems in cars are designed as multi-input systems to maintain a driver's desired speed while compensating for external disturbances such as changes in terrain. The block diagram for a cruise control system typically includes two main inputs: the desired speed set by the driver and any external disturbances, such as the incline of the road. By adjusting the engine throttle, the system maintains the vehicle's speed as close to the desired value as possible.
In the absence...
Proportional-Derivative (PD) control is a widely used control method in various engineering systems to enhance stability and performance. In a system with only proportional control, common issues include high maximum overshoot and oscillation, observed in both the error signal and its rate of change. This behavior can be divided into three distinct phases: initial overshoot, subsequent undershoot, and gradual stabilization.
Consider the example of control of motor torque. Initially, a positive...
The hierarchy of motor control refers to the different levels of organization and processing involved in controlling movement in the body. These levels range from higher cortical areas involved in planning and decision-making to lower spinal cord reflexes that respond automatically to external stimuli.
Segmental Level: This is the lowest level of motor control and consists of spinal cord segments. It is responsible for generating simple reflexes and rhythmic movements such as walking. Neural...
