389. Request ACC

The press_ACC_main_button() turns on Adaptive Cruise Control (ACC). The press_ACC_set_button() scenario activates Adaptive Cruise Control for the Ego (DUT) driver and sets the desired cruise speed. The press_ACC_cancel_button() scenario deactivates ACC.

389.1 FRun parameters

Parameter Description Range
acc_cruise_speed The cruise speed set when ACC is on. Default is 40kph.

389.2 Coverage metrics

Item Unit / Type Range Description
acc_main_switch bool Indicates whether ACC was activated.
acc_ego_min_acceleration mpsps [-7..0] The Ego's min acceleration while ACC was on
acc_ego_max_acceleration mpsps [0..8] The Ego's max acceleration while ACC was on
ego_speed_at_active_cc_state_end kph [0..150] The speed of the Ego at the end of the active_cc state
ego_speed_while_acc_active kph [0..150] The speed of the Ego when ACC is activated
acc_cruise_speed kph [10..140] The ACC set cruise speed
acc_cruise_distance safety_time_gap The ACC set cruise distance

389.3 KPIs

KPI Unit / Type Description
acc_cruise_distance_at_acc_activation kph The ACC cruise distance upon activation.
acc_cruise_speed_at_acc_activation safety_time_gap The ACC cruise speed set by the driver upon activation of ACC.
acc_on_time time The amount of time ACC was turned on during the run.

389.4 Trace

Item Unit / Type Description
acc_state acc_state_v2 The state of ACC

389.5 Checks

Check Default severity Issue kind Default threshold Description
acc_is_on warning ACC_checks false ACC mode was not turned on at any time during the scenario.
acc_is_off_in_mid warning ACC_checks false ACC turns off during the scenario.
acc_max_acceleration warning The max acceleration of the Ego, which gives a warning if it is not in safe range
acc_min_acceleration warning ACC_checks -3.5mpsps Minimum acceleration of the Ego, which gives warning if it is not in safe range
acc_max_jerk warning ACC_checks 2mpspsps The maximum jerk of ego, which gives warning if it is not in recommended safe range
acc_min_jerk warning ACC_checks 0.3mpspsps The minimum jerk of the Ego, which gives warning if it is not in recommended safe range
