According to the official VBox figures, the Venom – powered by a 7-litre twin-turbo General Motors-sourced V8, remember – accelerated from 20mph to 120mph in just 7.71 seconds, pulling a maximum 1.2g of longitudinal acceleration as it went.
The characteristic shape suggests a method to parameterize the g-g diagram by means of a diamond shape, with a, b, and c representing the maximum longitudinal, lateral and braking accelerations as shown in Fig. 11 (see details in Sec. IV).
The mushroom cap, from −0.5 m/s2 to 2 m/s2 longitudinal acceleration, occurs when the accelerator is used and brake is not.
The collected data include steering angle, speed, longitudinal acceleration, lateral acceleration, yaw rate, accelerator control, brake control, lateral displacement, longitudinal displacement, accelerator control speed, and brake control speed.
Five performance attributes, namely speed, longitudinal acceleration, lateral acceleration, yaw rate, and throttle position were used to describe the driving behavior.
This reference speed was formulated by taking into account the vehicle's limits due to lateral acceleration, combined lateral and longitudinal acceleration and the vehicle's performance capabilities.
Human longitudinal acceleration.
Given that passengers may stand facing in any direction within the vehicle, the resultant of the lateral and longitudinal acceleration was calculated for each measured point and filtered to remove high frequency vibration in order to give the maximum quasi-static acceleration in the horizontal plane.
Acceleration is proportional to the square of speed, meaning that driving occurs at constant velocity 3) Human longitudinal acceleration .
Unlike lateral acceleration, longitudinal acceleration appears to be, at least at this global level, loosely related to speed.
