1. A vehicle comprising:
(a) a controller area network (CAN) comprising a data bus and a plurality of nodes comprising electronic control units (ECUs) connected to the data bus for electronic communications, the plurality of nodes comprising,
(i) a main control module (MCM) that receives a plurality of input signals, wherein the MCM controls engine operations comprising acceleration based on the electronic communications;
(ii) a cruise control module that communicates with the MCM for controlling a speed of the vehicle when the cruise control module is engaged; and
(iii) an intelligent speed limiter (ISL) module of a closed intelligent speed adaptor (ISA) system, wherein the ISL module that communicates, to the MCM, a signal corresponding to depression of an accelerator pedal of the vehicle for controlling acceleration of the vehicle by the MCM;
(b) a throttle position sensor module that provides a signal, corresponding to depression of an accelerator pedal of the vehicle, directly to the ISL module for communication to the MCM, wherein the ISL module modifies the signal for limiting the speed of the vehicle when the speed of the vehicle is determined by the ISL module to be within a range of or exceeding an allowed speed;
(c) a brake switch connected to the MCM, wherein the brake switch provides one or more signals to the MCM indicative of vehicle braking which results in disengaging the cruise control when the cruise control is engaged; and
(d) a simulating controller connected in parallel to the brake switch and to the MCM, wherein the simulating controller provides one or more signals to the MCM indicating vehicle braking for disengaging the cruise control when
(A) the speed of the vehicle is determined to be within a range of or exceeding an allowed speed, and
(B) if the cruise control is determined to be engaged,
such that the effectiveness of the ISA system to limit the speed of the vehicle to an allowed speed by controlling acceleration of the vehicle by the MCM is unaffected by the cruise control module.
